A missile capture scheme based on conical-like scan method

Abstract

A scheme based on conical-like scan method is proposed to solve the problem of the missile capture with phased array radar. The factors, which affect the missile capture process, are analyzed. The direction cosine measurement variance, which is the main factor dealing with the radar signal processing, is decreased by applying the weighed least square estimator with conical-like method. The measurement variance is derived and different beam packing arrangements are discussed. The triangular packing arrangement, as an example, is specially analyzed. Finally the scheme is described step by step to fit for programming.
