摘要
推导出任意合成宽带波形下目标回波的通用模型,并分析了引起合成距离像失真的原因。基于分析结果,提出了一种新的合成距离像失真分析方法和误差评估准则。同时,从理论上讨论了运动目标特性与被提出误差评估准则之间的关系。仿真结果证实了理论分析的准确性。
The general model of target echo signal was derived for any synthetic wideband waveforms,and some reasons causing the distortion of synthetic range profile were analyzed.A novel method and a new criterion were proposed based on the results.At the same time,the relationship between a moving target's characteristic and the proposed criterion is theoretically evaluated in detail.Simulation results show that the analysis conclusions are accurate.
