Clutter-Sensing-Driven Space-Time Adaptive Processing Approach for Airborne Sub-Array-Level Digital Array

Remote Sensing
Sub-array-level digital arrays effectively diminish the computational complexity and sample demand of space-time adaptive processing (STAP), thus finding extensive applications in many airborne platforms.

Sea Clutter Suppression Method Based on Pyramid Multiscale Residual Attention Generative Adversarial Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Sea clutter significantly impacts radar maritime target detection. Existing methods still show limited clutter suppression performance, and their generalization ability requires further improvement. To address this issue, a sea clutter suppression method

Amplitude suppression of nongaussian sea clutter in a noncoherent bandpass path of the receiver

Известия высших учебных заведений России: Радиоэлектроника, 2016
The method of non-linear amplitude suppression of radar clutter from a sea surface in a noncoherent band path of the receiver is considered. The model of the most adequate nongaussian a radar clutter from the rough sea surface which envelope is based on ...
