A signal-to-noise ratio enhancement method for non-cooperative bistatic radar system

In non-cooperation bistatic radar system, the target detection performance of the system is degraded by the background clutter and random noise. In order to solve this problem, a new method based on signal phase matching for signal-to-noise ratio (SNR) enhancement is proposed. It fully uses the phase differences of target signals and interference signals. The target signals are successfully separated from the background clutter and random noise according to the signal phase matching. The simulation results show that this method can effectively suppress the background clutter and random noise and remarkably enhance the SNR of the non-cooperation bistatic radar system, which has important and practical significance in improving the target detection performance of the non-cooperation bistatic radar system.
