A multi-norm constraints sparse recovery STAP with coprime sampling structure under array sensor failures

Egyptian Informatics Journal
The coprime sampling structures offer significant advantages in achieving large apertures and high degree of freedom (DOF), but sensor failures can severely impact their space time adaptive processing (STAP) performance.

Subband Array Implementations for Space-Time Adaptive Processing

, 2005
Intersymbol interference (ISI) and cochannel interference (CCI) are two primary sources of signal impairment in mobile communications. In order to suppress both ISI and CCI, space-time adaptive processing (STAP) has been shown to be effective in ...

The relative merits of pre-/post-Doppler STAP

, 2022
When considering possible implementations of space-time adaptive processing (STAP) techniques, it is apparent that there are two principal approaches; STAP before Doppler filtering (pre-Doppler STAP) and STAP after Doppler filtering (post-Doppler STAP ...

Fast Iterative Subspace Algorithms for Airborne STAP Radar

EURASIP Journal on Advances in Signal Processing, 2006
Space-time adaptive processing (STAP) is a crucial technique for the new generation airborne radar for Doppler spread compensation caused by the platform motion. We here propose to apply range cell snapshots-based recursive algorithms in order to reduce

Collaborative Nonlinear Space-time Adaptive Processing and Pulse Compression Based on Neural Networks

Leida xuebao
Traditional airborne radar Pulse Compression (PC) and Space-Time Adaptive Processing (STAP) suffer performance degradation in complex target and clutter environments due to their reliance on predefined linear models. To address this issue, we developed a
