Robust detection in continuous-wave noise radar – experimental results

In the paper the problem of target detection in continuous-wave noise radar in the presence of impulsive external noise is addressed. If received noise has distribution different than Gaussian, the classical correlation receiver does not provide the optimal results and the performance of the radar is seriously degraded. In order to restore the sensitivity lost due to the impulsive noise a robustification method is proposed. In the method a nonlinear function is applied to the signal in order to remove the outliers. The method is verified on real-life signals.
