A radar weak signal detection method based on nonlinear spatial spectral analysis

Combining nonlinear science, bionics an system identification theory, this paper proposes a modern nonlinear spatial spectral analysis method to deal with the problem of weak signal detection of conventional coherent an non-coherent radars, breaking through the traditional radar signal detection theory an method, and tested on the radar weaksignal detection system based on DSP+FPGA, the results show that it can significantly improve the detection ability of radar.
