Abstract : MMING, PERFORMANCE(ENGINEERING)CHAFFThe final report on an adaptive radar techniques is contained in two volumes. The second volume discusses angle tracking with adaptive array radar. Volume I discusses adaptive array antenna techniques for ground-based radar and contains a generalized computer program for investigation of adaptive array radar in an environment containing jammers and/or distributed clutter. In many-element arrays, complexity can be reduced by forming subarray outputs which are then combined with adaptively controlled weights. This reduces the number of adaptive control circuits at some cost in array performance. Various types of subarraying are compared. The report also discusses the use of a notched-omni transit signal to permit adaptive sidelobe reduction when clutter or chaff extends into the main beam. Performance of various adaptive antenna configurations in a blinking jammer environment is considered. (Author)
