Unmanned aerial vehicle finding and early warning device
2016
The invention provides an unmanned aerial vehicle finding and early warning device, which comprises a direction-finding antenna array module, a signal receiving module, a spectrum analysis module, an analysis result display host, a video monitoring module and an early warning module. The spectrum analysis module acquires distribution of signal frequencies and signal values through frequency domain signals, the signal values and the stability are judged, interference signals are distinguished through setting of a signal threshold and a stability threshold, and unmanned aerial vehicle signals can be precisely judged. The direction-finding antenna array module can scan radio signals in each direction in a distributed control range. After the unmanned aerial vehicle signals are judged, the video monitoring module can track and acquire the video in the direction in real time, and early warning is carried out through the early warning module.
