Range-recursive space-time adaptive processing (STAP) with a circular airborne radar antenna

2008 IEEE Radar Conference, 2008
In this paper, space-time adaptive processing (STAP) for clutter rejection in airborne radar is considered using a uniform circular antenna array. Indeed, this technique is usually employed in case of a uniform linear antenna array while the advantages of a circular antenna were recently highlighted [2]. Our contribution is two fold.

A comparison study between Wiener and adaptive state estimation (STAP-ASE) algorithms for space time adaptive radar processing

SPIE Proceedings, 2010
Space Time Adaptive Processing (STAP) is a multi-dimensional adaptive signal processing technique, which processes the signal in spatial and Doppler domains for which a target detection hypothesis is to be formed. It is a sample based technique and based on the assumption of adequate number of Independent and Identically Distributed (i.i.d ...

GPU-based space-time adaptive processing (STAP) for radar

2013 IEEE High Performance Extreme Computing Conference (HPEC), 2013
Space-time adaptive processing (STAP) utilizes a two-dimensional adaptive filter to detect targets within a radar data set with speeds similar to the background clutter. While adaptively optimal solutions exist, they are prohibitively computationally intensive.

Performance modeling and optimization framework for space-time adaptive processing (STAP)

18th International Parallel and Distributed Processing Symposium, 2004. Proceedings., 2004
Summary form only given. Fully-adaptive space-time adaptive processing (STAP) is an optimal but impractical radar processing algorithm due to the overwhelming number of operations required. Hence, many different heuristic approaches are sought to approximate the optimal method with fewer number of operations.

Space-time adaptive processing (STAP) with limited sample support

Proceedings of the 2004 IEEE Radar Conference (IEEE Cat. No.04CH37509), 2004
A particularly active area of research in space-time adaptive processing (STAP) involves scenarios in which the sample support available for training the adaptive processor is limited. Several of these scenarios are of significant current interest.

A new approach to wideband space-time adaptive processing (W-STAP)

Processing Workshop Proceedings, 2004 Sensor Array and Multichannel Signal, 2005
This paper presents a new methodology for airborne wideband space-time adaptive processing (W-STAP) radar systems. In W-STAP, the wideband target signal is first decomposed into a series of narrowband signals. This is referred to as a sub-banding process.

Benefits of space–time adaptive processing (STAP) in bistatic airborne radar

IEE Proceedings - Radar, Sonar and Navigation, 2003
The paper investigates the merits of using STAP for clutter suppression in bistatic airborne radar. Particular emphasis is placed on the clutter angle-Doppler inter-relationships in bistatic geometries, and it is demonstrated that there can be ground regions where small changes in arrival angle imply large changes in the Doppler shift.
