Abstract

To improve the detection accuracy of the radar security system and reduce the probability of false alarms, a Range-Doppler multi-target detection method based on classical spectrum estimation is proposed to solve the problem that the triangular modulation waveform sent by FMCW radar produces false targets in multi-target detection.In this method, the echo signal is constructed to generate a signal matrix by the difference value filling zero,the range Doppler image is drawn, and the target information is obtained by processing the image, which effectively avoids the interference of false targets.Combined with the security early warning strategy of the security system, the software design of the system is completed.The simulation results show that under the interference of Gaussian white noise, the Range-Doppler multiple target detection method based on classical spectrum estimation has higher accuracy and faster speed under the same conditions, which can improve the reliability of the security system.
