초록 ▼

A system for providing integrated detection and countermeasures against unmanned aerial vehicles include a detecting element, a location determining element and an interdiction element. The detecting element detects an unmanned aerial vehicle in flight in the region of, or approaching, a property, place, event or very important person. The location determining element determines the exact location of the unmanned aerial vehicle. The interdiction element can either direct the unmanned aerial vehicle away from the property, place, event or very important person in a non-destructive manner, or can cause disable the unmanned aerial vehicle in a destructive manner.

1. A target detection system for detecting small unmanned systems such as drones, the target detection system comprising: a first data connection that receives (a) radar-detected azimuth and elevation data of a target and (b) target range information;a second data connection that receives radio frequency spectral analysis data of target radio frequency signals that identifies or classifies the target; andat least one processor operatively coupled to the first and second data connections, the at least one processor including a direction and range estimation processor configured to develop, from the received azimuth and elevation data and the target range information, data indicating target location in a three-dimensional coordinate system where three coordinates specify the position of the target in three-dimensional space. 2. The system of claim 1 wherein the direction and range estimation processor is configured to develop data indicating said target location for unmanned systems including unmanned aerial systems weighing less than 55 pounds. 3. The system of claim 1 wherein the radar-detected azimuth and elevation data comprise data detected by a low power x-band radar. 4. The system of claim 1 further including a further data connection that receives azimuth and elevation data of the target an optical sensor detects independently of the radar, wherein the direction and range estimation processor uses both the azimuth and elevation data detected by the optical sensor and the azimuth and elevation data detected by the radar. 5. The system of claim 1 wherein the at least one processor produces sensor movement control signals to control tracking movement of at least one sensor, and the at least one processor produces tracking data values to slew the tracking movement of the at least one sensor thereby tracking the target. 6. The system of claim 5 wherein the at least one sensor comprises a directional radio frequency receiving antenna connected to RF spectrum analysis hardware and software that produces the radio frequency spectral analysis data. 7. The system of claim 1 further comprising a further data connection that provides radio frequency receiver data corresponding to signals received by an omnidirectional radio frequency receiving antenna and a directional radio frequency receiving antenna. 8. The system of claim 1 wherein the at least one processor is configured to produce classification data that classifies objects of interest as targets and identifies unmanned vehicles utilizing multiple databases or libraries created and categorized with spectral signatures for unmanned vehicles. 9. The system of claim 8 wherein the spectral signatures include sound, heat, radar data, and/or radio frequency wave pattern. 10. The system of claim 1 further including a direction finding receiver configured to produce search data for the target. 11. The system of claim 1 wherein the at least one processor is configured to produce data that controls the direction of an automatic antenna alignment device to thereby track the target. 12. A target detection system for detecting small unmanned systems including drones, the target detection system comprising: at least one radar configured to detect first azimuth and elevation data of a target;at least one optical sensor configured to detect second azimuth and elevation data of the target;at least one of the radar and the optical sensor producing target range information;at least one radio frequency receiver configured to identify the target using radio frequency spectral analysis of radio frequency signals received from the target; andat least one processor operatively coupled to the at least one radar, the at least one optical sensor and the at least one radio frequency receiver, the at least one processor including a direction and range estimation processor configured to use the first and second detected azimuth and elevation data and the range information to determine target location in a three-dimensional coordinate system where the target location comprises three coordinates that together specify the position of the target in three-dimensional space. 13. The system of claim 12 wherein the system is configured to detect unmanned aerial targets that weigh less than 55 pounds. 14. The system of claim 12 wherein the radar comprises a low power xband radar. 15. The system of claim 12 wherein the optical sensor detects azimuth and elevation data of the target independently of the radar. 16. The system of claim 12 wherein the at least one processor produces sensor movement signals, and implements slew to cue to track the target. 17. The system of claim 16 wherein the at least one sensor comprises a directional radio frequency receiving antenna that tracks the target using the slew to cue. 18. The system of claim 12 further comprising an omnidirectional radio frequency receiving antenna and a directional radio frequency receiving antenna configured to receive radio signals emitted by the target. 19. The system of claim 12 wherein the at least one processor detects and identifies unmanned vehicles utilizing a database library comprising spectral signatures. 20. The system of claim 19 wherein the spectral signatures include sound, heat, radar cross-section, and/or radio frequency wave pattern. 21. The system of claim 12 further including a direction finder to search for the target. 22. The system of claim 12 wherein the at least one processor controls the direction of an automatic antenna alignment target tracker. 23. The system of claim 12 wherein the at least one processor performs image recognition algorithms.
