Adaptive Airborne Radar Simulation with Equalization Filter Taps

Abstract

Space-time processing (STP) provides an adaptive filter for an airborne phased-array radar to detect targets m clutter and jamming that have spatial and Doppler spread. We developed a flexible airborne radar simulation to identify limitations in the techniques and to evaluate the capabilities of different STP designs. One of the space-time architectures, jointly adaptive STP in the element space, employs joint processing of array elements and pulse train data. The array elements provide the azimuth (spatial) information, and the pulse repetition interval (PRI) taps or pulses provide the Doppler information required to form the two-dimensional azimuth-Doppler filter. In the adaptive mode, additional temporal information from taps separated by a sampling rate interval (greater than Nyquist) provide additional degrees of freedom to mitigate interference due to wideband, narrowband, and multipath jamming. This paper discusses the theory and implementation of STD using temporal equalization filter taps, and presents three different examples illustrating the features of the simulation....STP, Radar, Simulation, Adaptive airborne radar.
