Two key problems of fast target acquisition in array radar are studied: angle measurement and angle prediction.Firstly, this thesis studies the fastness of array radar from the angle measurement principle, the required wave position arrangement, discrimination characteristics and the angle measurement performance, The two kinds of angle measurement algorithms are intercepted by the target: one pulse of amplitude comparison and amplitude weighted average, and the guidance and nonlinear correction methods of these two algorithms in engineering application are proposed. Then, the angle prediction algorithm using tracking filter is analyzed, Proposed the SDF tracking filter; finally, carried on the simulation research in a certain array radar simulation system.
