Target Detection in Continuous-Wave Noise Radar in the Presence of Impulsive Noise

In the paper a problem of target detection in continuous-wave noise radar in the presence of impulsive external noise is addressed. Noise radar uses random or pseudo-random waveform as a sounding signal. Classical correlation receiver used in noise radar is optimal for external noise with Gaussian distribution. If the external noise has distribution different than Gaussian, for example impulsive noise, the performance of the detection is 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.
