Clutter-Masked Waveform Design for LPI/LPD Radarcom Signal Encoding
Sensors, 2021 In this work we propose a method of in situ clutter deconvolution and modeling using experimentally obtained UWB radar data. The obtained clutter models are then used for random sequence encoding of radar-communication (radarcom) signals to achieve ...

Enhanced Pre-STAP Beamforming for Range Ambiguous Clutter Separation with Vertical FDA Radar
Remote Sensing, 2021 Medium pulse repetition frequency (MPRF) is an important mode in airborne radar system. Since MPRF mode brings both Doppler and range ambiguities, it causes difficulty for the airborne radar to suppress ground or sea clutter. In recent years, it has been

Sea Clutter Suppression for Radar PPI Images Based on SCS-GAN
IEEE Geoscience and Remote Sensing Letters, 2021 The problem of strong sea clutter, e.g., sea spikes, may bring in low signal-to-clutter ratio (SCR) and cause great interference to radar marine target detection.
