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...
This paper presents a robust detection scheme for continuous wave noise radar in the presence of heavy-tailed interferences described by alpha-stable probability distributions. The conventional detection algorithm based on second order statistics may reveal significant performance degradation in the presence of impulsive noises. A substantial advantage of presented robust algorithm based on lower...
A new class of signal processing algorithm based on CLEAN methods primary introduced in radio-astronomy is presented in the paper. The classical radar signal processing is based on match filtering concept, which is optimal in mean square sense in case, when single target echo is detected against white or colour Gaussian noise. Such approach was effective when pulse radar have been widely used. The...
A new method for quality enhancement in a noise synthetic aperture radar (SAR) image and the first results of its application to the SAR image generated with the use of a bistatic Ka-band ground-based noise waveform SAR (GB NW-SAR) are presented. A SAR image generated with a noise SAR suffers from the masking effect which is tied to residual random fluctuations in noise radar response from bright...
