Adaptive antenna nulling performance in a dispersive propagation medium
Abstract
The Signal-to-Interference pulse Noise Ratio (SINR) performance of a generic Multi-Beam Antenna (MBA) and a Thinned Phased Array Antenna (TPAA) is evaluated for multiple jammer scenarios including the effect of angle-of-arrival distortion of the jamming signals caused by a striated propagation media. The analysis is based on computer modeling of the antenna configurations using the optimal Wiener solution for the adaptive weight calculations. Statistically distributed SINR values in fading are obtained by applying the equivalent effect of independent two-dimensional sample functions of spatially varying flat fading at the antenna aperture.
