Detection of Fast Air Maneuvering Targets via STAP
摘要
Abstract
Space-time adaptive processing is an effective method for moving target detection in airborne radar.However,high speed of air targets induce serious range walk and Doppler ambiguity.To make things worse, acceleration of the target will result in Doppler spread.To detect the above mentioned fast air maneuvering targets, a new method is proposed in this paper, which removes the clutter before Keystone formatting,hence the effects of Keystone formatting for the ambiguous targets' range walk compensation on the clutter distribution and further on the performance of STAP can be avoided.The Doppler spread of the target is compensated by the estimated acceleration via Wigner-Hough transform.Therefore, good detection performance of fast air maneuvering targets can be achieved.Effectiveness of the new method is verified via simulation examples.关键词
