Based On The Airborne Radar Data Processing Algorithm Simulation Study

It goes without saying that the importance of air power in modern warfare. As an important factor to affect the efficiency of warplanes, the role of airborne radar becomes vital important. Due to the relative motions between airborne platform and the targets, and the influence of the plane itself, the data processing is more difficult in relation to other fixed platform. Based on an airborne radar simulation software project, this paper does some research on airborne radar data processing.First, in term of the question of the observation and processing of the airborne radar's data in a different coordinate system, with a detailed analysis of the process from the antenna array coordinate system to the earth right angle system, and simulate the transformation of covariance in different coordinate.Second, from the angle of engineering, do some research on several typical track initiation methods, including direct-vision method, logic method and Hough transfer method. Due to the operations of the Hough transfer method based on processing batch is too much to achieve in project, this paper emphatically researches the direct-vision method with the limit of speed, acceleration and angle, and the logic method based on sliding-windows.Third, do some research on the data association, for example, the PDAF algorithm which is suitable for single goal environment and the JPDA algorithm which is suitable for multi-objective environment, and simulate several representative maneuvering target tracking algorithm, in particular the IMM algorithm.Finally, in term of previous work, combined the elliptical goal with limited speed, acceleration and angle, combined with IMM_PDAF algorithm, the simulate results show that this method can effectively reduce the number of clutters of the gate under some conditions, which improve the quality of association and tracking.
