Weak target detection technology of passive radar on the navigation satellite signal

Weak target detection technology of passive radar on the navigation satellite signal

The passive radar detection system receives secondary reflection signal by the navigation satellite signal. The secondary reflection signal is too weak to detect the target. The method to improve the signal-to-noise ratio (SNR) of weak targets is proposed based on the accumulation algorithm. First,...
