Performance of two Low-Rank STAP Filters in a Heterogeneous Noise [PDF]
, 2013 International audienceThis paper considers the Space Time Adaptive Processing (STAP) problem where the disturbance is modeled as the sum of a Low-Rank (LR) Spherically Invariant Random Vector (SIRV) clutter and a zero-mean white Gaussian noise. To derive

Fast-time STAP performance in pre and post range processing adaption as applied to multichannel SAR [PDF]
, 2006 Hot-clutter cancellation using fast-time Space Time Adaptive Processing (STAP) can occur either pre or post range processing (RP) and to date, there has not been a direct comparison on which method offers the best results. This paper provides an analytic

MIMO radar space–time adaptive processing using prolate spheroidal wave functions [PDF]
, 2008 In the traditional transmitting beamforming radar system, the transmitting antennas send coherent waveforms which form a highly focused beam. In the multiple-input multiple-output (MIMO) radar system, the transmitter sends noncoherent (possibly ...

An adaptive detection of spread targets in locally Gaussian clutter using a long integration time [PDF]
, 2012 This paper deals with the problem of detecting a collision target in ground clutter, using a long integration time. A single reception channel being available, classical space time adaptive processing (STAP) cannot be used. After range processing, ground

Robust STAP With Reduced Mutual Coupling and Enhanced DOF Based on Super Nested Sampling Structure
IEEE Access, 2019 In practical airborne radar, mutual coupling between array elements usually leads to space-time steering vector distortion for space-time adaptive processing (STAP), which seriously degrades radar performance.
