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.

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.

On the benefits of space-time adaptive processing (STAP) in bistatic airborne radar

RADAR 2002, 2003
This paper has examined the clutter angle-Doppler inter-relationships for bistatic airborne radar. It has been shown that there are significant differences between the monostatic and bistatic clutter rejection problems. In particular, it has been shown that bistatic airborne radar clutter exhibits the following characteristics: 1.

Robust space–time adaptive processing (STAP) in non-Gaussian clutter environments

IEE Proceedings - Radar, Sonar and Navigation, 1999
The problem of space-time adaptive processing (STAP) in non-Gaussian clutter is addressed. First, it is shown that actual ground clutter returns are heavy-tailed and their statistics can be accurately characterised by means of alpha-stable distributions.

Canonical framework for describing suboptimum radar space-time adaptive processing (STAP) techniques

Proceedings of the 2004 IEEE Radar Conference (IEEE Cat. No.04CH37509), 2004
We address the problem of detecting slow moving targets from a moving radar system using space-time adaptive processing (STAP) techniques. Optimum interference rejection is known to require the estimation and the subsequent inversion of an interference-plus-noise covariance matrix. To reduce the number of training samples involved in the estimation and

A pragmatic approach to adaptive antennas and space-time adaptive processing (STAP)

2000 5th International Symposium on Antennas, Propagation, and EM Theory. ISAPE 2000 (IEEE Cat. No.00EX417), 2000
Summary form only given. In the conventional adaptive beamforming methodology typically weights are connected to each one of the antenna element in the array and the processing information is generated over time, as the correlation matrix of the data needs to be formed.

Space-Time Adaptive Processing (STAP) for Low Sample Support Applications

2004
Abstract : Airborne radar Space-Time Adaptive Processing (STAP) in a heterogeneous, target-rich environment is addressed. An efficient Kalman Filter implementation of the normalized form of the Parametric Adaptive Matched Filter (NPAMF) is introduced and shown to perform well against a detailed simulation of a site-specific, dense-target environment ...

On modeling and hardware implementation of Space-Time Adaptive Processing (STAP) for target detection in passive BI-static radar

2012 11th International Conference on Information Science, Signal Processing and their Applications (ISSPA), 2012
This paper presents the modeling and partial FPGA implementation of Space Time Adaptive Processing (STAP) algorithm for Passive Bi-static Radar (PBR) using commercial FM transmitter as illuminator of opportunity. Two simulated targets were inserted in the real-time recorded FM eight channel data signal.

Computation reduction in space time adaptive processing (STAP) of radar signals using orthogonal wavelet decompositions

Conference Record of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers (Cat. No.00CH37154), 2002
The STAP of radar signets involves solving a set of linear equations /spl Lambda/w=s. Here /spl Lambda/ is the correlation matrix of noise plus interference signals, w is the weight vector and s is the steering vector. The Weiner solution to estimate the optimum weight vector w/sub 0/ for a given s that minimizes the effect of the interference signal ...

Space-time adaptive processing (STAP) for wide-band airborne radar

Record of the IEEE 2000 International Radar Conference [Cat. No. 00CH37037], 2002
STAP is a technique used to reject clutter returns in airborne phased array radar systems. This paper presents an investigation of the performance of STAP in wideband scenarios. It is shown that, under these circumstances, narrowband STAP is often sufficient for clutter rejection with sideways looking arrays, but that a wideband STAP architecture is ...
