Space-Time Adaptive Processing Using Pattern Classification
IEEE Transactions on Signal Processing, 2015Since it was first developed to solve the problem of target detection by moving target indicator (MTI) radars, space-time adaptive processing (STAP) has seen many versions, developed to overcome the shortcomings of the original version. In this paper, we introduce a new method, called Learning-Based Space-Time Adaptive Processing (LBSTAP), in which the

A maximum entropy framework for space–time adaptive processing [PDF]
Signal Processing, 2004 We address the problem of devising and analyzing radar processors for space-time adaptive processing applications. We first define a class of adaptive filters based on the approximation of the overall disturbance with a multichannel autoregressive process.

Space-Time Adaptive Processing and Jamming [PDF]
, 2018 Space-time adaptive processing (STAP) has been a well-established technique, whose basic concept and theory are first put forward by Brennan and Reed. However, it is difficult to implement in the practical system because of the computational complexity and the sample limitation for estimating the clutter covariance matrix.

A Cognitive Architecture for Space Time Adaptive Processing
2020 IEEE International Radar Conference (RADAR), 2020A cognitive radar can be conceived as a system that is able to autonomously and continuously change the parameters of both the transmitter and the receiver to optimise its performances in changing complex and changing environment with the available resources.

Adaptive pulse design for space-time adaptive processing
2012 IEEE 7th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2012Space-time adaptive processing (STAP) is used in radar to adaptively suppress both ground clutter returns and radio frequency interference (RFI). However, RFI suppression utilizes degrees-of-freedom that would otherwise be applied to clutter suppression.

Multi-Waveform Space-Time Adaptive Processing
IEEE Transactions on Aerospace and Electronic Systems, 2017A new form of space-time adaptive processing (STAP) is presented that leverages additional training data obtained from waveform-diverse pulse compression filters possessing low cross-correlation with the primary waveform that is used for traditional airborne and space-based ground moving target indication.

Parallel algorithms for space-time adaptive processing
Proceedings of 9th International Parallel Processing Symposium, 2002We examine the signal processing problem of space-time adaptive processing (STAP) from a computational point of view. Specifically, we implement an STAP algorithm on the IBM PowerParallel SP1 computer. The two main challenges are solving multiple least squares problems simultaneously and finding an efficient way of implementing multiple computational ...

Knowledge-Aided Space-Time Adaptive Processing
IEEE Transactions on Aerospace and Electronic Systems, 2011A fundamental issue in knowledge-aided space-time adaptive processing (KA-STAP) is to determine the degree of accuracy of the a~priori knowledge and the optimal emphasis that should be placed on it. In KA-STAP, the a priori knowledge consists usually of an initial guess of the clutter covariance matrix.

Beam-augmented space-time adaptive processing
1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999Combined monostatic clutter (MSC) and terrain scattered interference (TSI) pose a difficult challenge for adaptive radar processing. Mitigation techniques exist for each interference alone but are insufficient for their combined effects. Current approaches separate the problem into two stages where TSI is suppressed first and then MSC. The problem with

Space-time adaptive mismatch processing
2016 IEEE Radar Conference (RadarConf), 2016Conventional signal processing for GMTI radar (pulse-compression and STAP clutter-cancellation applied sequentially) results in significant losses when pulse-to-pulse waveform diversity is used, because of range-sidelobe modulation. This report describes STAMMP, a method for joint pulse-compression, beamforming, and Doppler processing that mitigates ...
