Effects of Antenna Mutual Coupling in Space-Time Adaptive Processing (STAP)

摘要

This report considers the impact of antenna mutual coupling on adaptive phased array radar signal processing. First, the impedance matrix is developed via the method of moments and utilized in an airborne phased array radar data generation code. Next, the effect of mutual coupling on the true and estimated covariance matrices is considered. Finally, performance results are considered for a space-time adaptive processing algorithm in terms of probability of detection as well as plots of the test statistics versus angle- doppler.
