摘要
计算机仿真是现代雷达研究中的重要技术之一,针对合成孔径雷达(SAR)成像中影响仿真结果的因素,从分析SAR发射信号和回波信号模型出发,运用Matlab软件对SAR的发射波形以及点目标成像进行了仿真,直观地反应了距离多普勒成像算法原理。最终通过仿真分析,总结了SAR成像中影响仿真结果的5项因素,而这5项因素在运用Matlab仿真过程中对成像质量的优劣有着至关重要的影响。
Computer simulation is one of the important technologies in the modern radar study. Aiming at the factor which affects simulation results in synthetic aperture radar（SAR）imaging,Matlab software is used to simulate SAR transmission wave-form and point target imaging to realize the analysis of SAR transmitted signal and echo signal model. It reflected the principle of distance Doppler imaging algorithm intuitively. Based on the simulation analysis,the five factors that affect SAR imaging simulation results are summarized,which has a critical influence on imaging quality in the Matlab simulation process.
