Adaptive antenna processor test results

Summary form only given. A two-element adaptive array processor (AAP) was designed, built and tested. The primary purpose of this development was to demonstrate the operational airborne utility and to quantify the amount of jam resistance improvement offered by the AAP when operating in conjunction with a tactical anti-jam (AJ) radio set employing fast frequency hopping. Performance was measured with and without the AAP against three spatially and frequency disjoint jammers in order to quantify the anticipated AJ improvement offered by the array. Using a 10% bit error rate as the performance figure of merit, it was shown that 53% of the azimuths achieved at least 20 dB of improvement over the radio operating alone, while greater than 75% of the azimuths realized greater than 15 dB.<>
