The present disclosure relates to a counter measure effector, particularly but not exclusively, to a counter measure effector against unmanned aerial vehicles. Other aspects of the present disclosure relate to a method of controlling a counter measure effector.
Unmanned vehicles, particularly unmanned aerial vehicles (UAV), are an increasingly common sight. Mostly civil in nature, these UAVs are typically harmless to the public. Examples include drones for aerial building observation or even delivery drones that have recently been tested by shipping companies. However, occasionally even such commercial, “off the shelf” drones are used by individuals or companies for industrial espionage to obtain confidential information from their competitors, as well as for other nefarious purposes. Other types of UAVs are used for military purposes, such as spying missions or even performing physical attacks on foreign territory. Military grade UAVs can be dangerous not only for military personnel but also for civilian life.
In view of the above, counter measure systems are known that may be used to neutralise threats caused by UAVs. Such counter measure systems typically include one or more electronic counter measure effectors (“ECM”, also known as jammers) configured to emit electromagnetic radiation towards UAVs to take over control and/or disable unauthorised UAVs.
Most ECMs use radio frequency (“RF”) signals to generate a neutralising effect on target UAV's and other autonomous threats. By its nature, emitted RF is incapable of being sensed by humans, in marked contrast to kinetic weapon systems, where human senses as to system operation include audio, visual, sensory and olfactory triggers.
The difficulty associated with the human inability to detect RF emitted from ECM raises safety concerns for operators of such equipment, as it is practically impossible for the operator to know when the system is in use. For example, RF emitted by ECM must not be directed at the wrong type of UAV or at the wrong time. In one scenario, a military grade UAV may carry a payload and thus should never be deactivated via RF emitted by the ECM when the UAV is located above inhabited areas.
It is an aim of the present disclosure to solve or at least ameliorate one or more problems of the prior art.

One or more embodiments of the present disclosure will now be described by way of example only, with reference to the accompanying drawings, in which:
In the following description and accompanying drawings, corresponding features of different embodiments are, preferably, identified using corresponding reference numerals.
The body 102 is ideally formed from a material configured to inhibit conduction of radio frequency (RF) signals. For example, the body 102 may comprise the polymer NylonXTM Additionally, or alternatively, the body 102 may comprise KevlarTM
RF antennas 108, 109 are provided adjacent to the body 102 such that, in use, the RF antennas 108, 109 are forward-facing. The RF antennas 108, 109 are configured both to transmit and receive RF signals. The RF antennas 108, 109 of this embodiment are cylindrical antennas.
The RF antennas 108, 109 may be detachably mountable on either side of the body 102.
Between the rear end 106 and the front end 104 of the ECM 100, there is provided a data interface for connecting the ECM 100 to a separate control unit (not shown). The data interface is in data communication with the RF antennas 108, 109. The body 102 is at least partially hollow. An internal conduit is thereby provided through the body 102 for communication of RF data between the RF antennas 108, 109 and the data interface. The communication of RF data is via cabling (not shown) disposed within the internal conduit of the body 102. The cabling is, preferably, electromagnetically (EMC) shielded.
The body 102 of the ECM 100 comprises a removable battery pack 122 and one or more hand-grips, such as a pistol-type 112 grip and a fore-grip (not shown) removably mounted to the body 102 of the ECM 100. Of course, depending on the design of the ECM 100, only a single grip component, in the form of a pistol-type hand-grip, for example, may be mounted to the ECM 100. By providing for two hand-grips to be mounted as stabilising components, however, the ECM 100 can be better stabilised by an operator, in use.
The ECM 100 of
The mounting rail 124 is arranged on an upper side of the body 102, particularly along a longitudinal direction of the body 102. The mounting rail 124 may be detached from the body 102 if required, by removal of securing screws (not shown). The attachment rail 124 may be a Picatinny rail or a Weaver rail, for example.
The telescopic sight 126 (also known as a scope) is an optical sighting device that comprises an optical system, such as a refracting telescope to allow the user to identify and aim at targets in the distance. The telescopic sight is equipped with a reticule (202,
A front view of an exemplary, simplified telescopic sight 200 is shown in
The telescopic sight 200 has a first state, in which the optical system has a first appearance (e.g.
In
It will be understood that illuminating the reticule with dots of various colours is only one way of changing the appearance of the optical system of the telescopic sight 200 between its first and second states. In other examples, the entire reticule may be illuminated in various colours. In yet other examples, the colour may not change but the reticule 206 may be illuminated with differently shaped light projections, such as dots, circles, squares, triangles, crosses etc, as long as the appearance in the first state of the optical system differs from the appearance of the second state.
Turning to
The control circuit comprises a first electric switch 304, a second electric switch 306 and a third electric switch 314. The first and second electric switches 304, 306 may be MOSFET switches, e.g. 30V P-channel MOSFET switches. The third electrical switch may be a bipolar transistor, e.g. a 45V NPN general purpose transistor.
The DC power supply 302 is directly connected to the source of the first and second electronic switches 304, 306. The DC power supply 302 is further connected to the gate of the first electronic switch 304 and to the collector of the third electronic switch 314. The drain of the first electronic switch 304 is connected to a first LED 308. The drain of the second electronic switch 306 is connected to a second LED 310. The first and second LEDs 308, 310 are connected to the ground 316.
A control signal input 312 is connected to the base of the third electric switch 314. The emitter of the third electronic switch 314 is connected to the gate of the second electronic switch 306 and ground 316.
In operation, when the ECM is turned on, the power supply 302 is active and supplies the first LED 308 with an electric current as long as the third electronic switch 314 remains closed. The third electronic switch 314 remains closed as long as the one or more antennas of the ECM remain inactive, i.e. the antennas do not emit any RF radiation. Once one or more of the antennas are activated, a control signal is provided via the control signal input 312 that is sufficient to open the third electronic witch 314. Once the third electronic switch 314 is open, the gate of the first electronic switch 304 will no longer be provided with sufficient current, such that the first electronic switch 304 will close. At the same time, the gate of the second electronic switch 306 will be provided with a current flow to open the second electronic switch 306, thereby connecting the power supply 302 with the second LED 310.
It will be understood that the above electronic circuit 300 is one example of a flip-flop circuit used to control the ECM in its first and second states. Of course, any other suitable electronic circuit may be used to provide this functionality.
In one example, the control signal input for opening the third electronic switch 314 may be provided by a control unit as soon as the control unit determines that one or more of the antennas are active. Alternatively, the control signal may be an analogue signal sent to the base of the third electronic switch 314 directly as the trigger of the ECM is activated. In this alternative, the trigger of the ECM may act to close a manual switch (not shown) for supplying the required collector emitter current. In this alternative, diodes in reverse order may be utilised to create the “or” function between the first and second states of the sight.
The circuit 300 enables two different appearances of the telescopic sight in the two different states. In the first state, i.e. when none of the antennas emit radiation, only the first LED 308 is active and projects its light onto the reticule. In the example of
In some embodiments, other information may be projected onto the reticule 206 in the first and/or second states of the optical system. In one example, such information may include operating parameters of the ECM 100, such as the chosen RF band, the orientation, or the battery status of the ECM 100.
Alternatively or additionally, the telescopic sight may be configured to project target-data representative of a target UAV onto the reticule. Such target-data may comprise one or more of a distance of the target UAV from the counter measure effector, an altitude at which the target UAV is located, a travel speed of the target UAV, or a communication bandwidth used by the target UAV. The target-data may either be obtained by the ECM itself, e.g. via the two antennas 108, 109, or by means of remote sensors. In some examples, radar or lidar sensors may be in communication with the ECM to provide at least parts of the target-data, such as the position, altitude, and/or travel speed of the target UAV. The control unit of the ECM may receive such target-data and control the telescopic sight to display said target-data, e.g. via a light projection onto the reticule 206.
It should be understood that, in the example of
Preferences and options for a given aspect, feature or parameter of the disclosure should, unless the context indicates otherwise, be regarded as having been disclosed in combination with any and all preferences and options for all other aspects, features and parameters of the disclosure.
