Abstract

An automated interactive antenna patterning apparatus depicts adaptive array antenna patterns and selects adaptive antenna array characteristics. The apparatus comprises an antenna modeling means building an adaptive antenna description, representing a number of antenna elements, means for determining angle-of-arrival, means for rank-ordering, means for sorting, means for antenna patterning and data output means providing composite antenna patterns for each array receiver. The adaptive antenna patterning apparatus better determines adaptive null steering antenna patterns produced in the presence of numerous interference sources. Also, automated interactive antenna patterning methods provide for depicting adaptive array antenna patterns and selecting adaptive antenna array characteristics, comprising the steps of forming an adaptive antenna description, determining angle-of-arrival, rank-ordering interference peaks, building a nulling table in a sorting means, calculating a total interference signal level and a signal to noise ratio plus interference ratio for each array receivers, forming an antenna pattern at the receivers, applying each pattern to determine nulled interference signal-to-noise level at each receiver and providing a data output means with the composite antenna pattern for each receiver. A computer-readable medium whose contents cause a computer system to depict adaptive antenna array characteristics as an article of manufacture is also provided.
