Multi-target Distance Measurement of Analytical Solution Chaotic Radar System
摘要
Abstract
For the problem of multi-target distance measurement of traditional chaotic radar system,a multi-tar-get distance measurement method based on analytical solution system is proposed. In the method,the continuous signal of the analytical solution chaotic system is designed as the radar transmit signal. The binary discrete se-quence of the analytical solution chaotic system is saved in the radar receiver by the shift register. The transmit signal copy can be reconstructed accurately by the saved binary discrete sequence in the radar receiver. The matched filter is then realized by the copy and the receiving signal. Target distance is obtained through the peak of the output of the matched filter. Multi-target distance measurement can be realized under -10 dB signal-to-noise ratio ( SNR) by the proposed method. Moreover,the storage is easily realizable and the cost is cheap since the radar receiver only needs to save the binary discrete signal which requires small space to store infor-mation. Finally,numerical simulations show the effectiveness of the proposed method.关键词
