Studies on Several Key-Problems of the Swift Target Acquisition in Array Radars

Two key-problems,angle measurement and angle prediction, of the swift targetacquisition in array radar are studied. Firstly, from the respect of required beamarrangement, discrimination feature and the performance of angle measurement, the twoalgorithms named amplitude-comparison monopulse-like algorithm and average weighted withamplitude algorithm, for measuring the targets angle with array radars are studied. Themethod for nonlinear adjustment when the average weighted with amplitude algorithm isapplied is posed. Then, the algorithms for predicting the targets angle with trackingfilters are analysed. A simple decoupled filter named SDF is presented. At last, thesealgorithms are tested in a simulation system for array radar.
