Radar Space-Time Adaptive Processing
Space-time adaptive processing (STAP) is a signal processing technique that was originally developed for detecting slow-moving targets using airborne radars. The general principle of STAP is as follows. The radar transmits a train of M coherent pulses. The echoes from potential targets (and clutter) are collected at each of the N elements of an antenna array. Separate receiver chains are attach...
متن کاملSpace-Time Adaptive Monopulse Processing for Airborne Radar in Non-homogeneous Environments
Space-Time Adaptive Processing (STAP) can be used in combination with monopulse techniques for the estimation of spatial and temporal parameters of moving targets in airborne radar. However, in non-homogeneous environment, the available amount of secondary data which have the same statistical characteristics with the clutter in the primary data is very limited. In this case, the optimum STAP is...
متن کاملArray Pattern Distortion and Remedies in Space–Time Adaptive Processing for Airborne Radar
Space–time adaptive processing (STAP) for airborne early warning radar has been a very active area of research since the late 1980’s. An airborne rectangular planar array antenna is usually configured into subarrays and then partial adaptive processing is applied to the outputs of these subarrays. In practice, three kinds of errors are often encountered, i.e., the array gain and phase errors ex...
متن کاملReduced Rank Space-time Adaptive Processing with Quadratic Pattern Constraints for Airborne Radar
Reduced rank (RR) linearly constrained minimum variance (LCMV) adaptive beamforming with quadratic pattern constraints (QPC) is applied to space-time adaptive processing (STAP) for airborne radar. The problem is formulated for general rank reducing transformations and main beam and sidelobe pattern control is achieved by imposing a set of inequality constraints on the mean-square error between ...
متن کاملDesign of Optimized Codes for Radar Space-Time Adaptive Processing
In this paper, we deal with the problem of constrained code optimization for radar Space-Time Adaptive Processing (STAP) in the presence of colored Gaussian disturbance. At the design stage, we devise a code design algorithm complying with the following optimality criterion: maximization of the detection performance under a control on the regions of achievable values for the temporal and spatia...
