Target Echo Simulation and Implementation Technology Based on Missile-Borne SAR Scene Matching Guidance

Abstract

AbstractAccording to the application characteristics of missile carrier’s scene-matching conductor system, such as the high moving speed of the missile carrier, high maneuverability and large PRF repetition frequency, combined with the SAR echo model, the key operations of the SAR target echo simulation are analyzed on the basis of studying the SAR target echo simulation algorithm. By using high-performance computing technology based on FPGA computing array, a method for real-time simulation of SAR echo based on range time domain pulse coherence is proposed. According to the key parameters such as carrier information, angle information, irradiation range, and occlusion judgment information of the missile-borne SAR radar platform, real-time simulation for large-area SAR target echo signals is realized, which can meet the application requirements such as large amount of calculation and high accuracy and real-time in the context of missile-borne SAR scene matching guidance.KeywordsMissile-borne SARScene matching guidanceTarget echo simulation
