GMTI performance estimation for airborne E-scan radar employing DPCA motion compensation

摘要

GMTI clutter rejection performance is conveniently represented by the Signal-to-Interference-Ratio Improvement Factor. The effects which limit SIR Improvement Factor, including clutter spectral width, platform motion and radar instability are reviewed and quantified. Calculation of SIR improvement factor and consequent detection performance will be described and illustrated for an E-scan radar employing DPCA for clutter motion compensation.
