Reduced rank space-time adaptive radar processing
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002This paper is concerned with the performance of reduced rank space-time adaptive processing (STAP) for radar signals. The motivation for rank reduction is that optimal full-rank STAP requires many more weights than can be supported on airborne and space-segment platforms.

Space-Time Adaptive Processing and Jamming
2018Space-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 novel space-time adaptive processing algorithm
Conference Record of the Thirty-Eighth Asilomar Conference on Signals, Systems and Computers, 2004., 2005We present a novel space-time adaptive processing (STAP) algorithm that can mitigate narrowband main beam interference. The bandwidth of the main beam interference has to be less than 50% of the bandwidth of the desired signal. The performance of the proposed beamformer is compared to a previously proposed one that cannot mitigate the main beam ...

Adaptive Space-Time Processing for Wireless CDMA
2003We consider adaptive space-time processing for wireless receivers in CDMA networks. Currently, the 2D RAKE is the most widely used space-time array-processor which combines multipath signals sequentially, first in space, then in time. We introduce incremental processing improvements to arrive ultimately at a more efficient one-dimensional joint space ...

Space-Time Adaptive Processing for Radar
2014Abstract Space-time adaptive processing (STAP) is an important radar technology. It is a cornerstone in the design of modern moving target indication and imaging radar systems. Specifically, STAP is a multidimensional filtering technique that mitigates the influence of clutter or radio frequency interference on principal radar products, viz.

Clutter modelling for space-time adaptive processing
IET Seminar on Radar Clutter Modelling, 2008The presence of clutter can be highly detrimental to detection of targets. STAP attempts to alleviate the problem by exploiting angle-Doppler inter-relationships to suppress clutter. The simulation of clutter data that is suitable for the application of STAP is considered in this paper.

Adaptive space-time signal processing and coding
MILCOM 2000 Proceedings. 21st Century Military Communications. Architectures and Technologies for Information Superiority (Cat. No.00CH37155), 2002This paper considers the capacities available in multi-antenna or MIMO systems through the use of techniques such as space-time coding. In particular we compare the conventional space-time coding systems so far developed which do not make use of knowledge of the channel at the transmitter, with the optimum adaptive system which adapts the transmission ...

Space-time adaptive processing for airborne radar
IEE Colloquium on Space-Time Adaptive Processing, 1998Advanced airborne radar systems are required to detect targets in the presence of both clutter and jamming. Ground clutter is extended in both angle and range, and is spread in Doppler frequency because of the platform motion. Space-time adaptive processing (STAP) refers to the simultaneous processing of the signals from an array antenna during a ...
