| description | The invention provides a static target intrusion detection algorithm based on a clutter spectrum background, and the algorithm comprises the steps: modulating a radar through employing a triangular wave continuous frequency modulation mode, obtaining a time-frequency relation between the transmitting and receiving signals of the radar, and calculating a target distance according to the time-frequency relation; acquiring an echo signal received by a radar, and performing adaptive filtering processing on the echo signal by adopting a minimum mean square algorithm to obtain a target time domain signal sequence; performing Fourier transform on the target time domain signal sequence to obtain a frequency domain pulse compression signal of the target; and detecting the frequency domain pulse compression signal by adopting a unit average constant false alarm detector algorithm to obtain a target signal in a detection result. According to the method, static target intrusion detection under the clutter spectrum backgr |
