摘要
同步是收发分置合成孔径雷达(SAR)成像的关键。本文建立了考虑时间同步误差的数学模型,进行了相位误差分析,并对点目标的距离压缩和方位压缩特性在不同的时间同步误差下作了仿真。通过仿真,验证了理论分析的正确性,从而为收发分置SAR系统设计中提出正确的时间同步要求提供了理论依据。
Synchronizations are the key to bistatic synthetic aperture radar(SAR) imaging. In this paper, a mathematical model considering the time synchronization error is given and a phase error analysis is performed. Range and azimuth compressions of a single point target are simulated for different time synchronization errors. The analysis, which is proved by simulations, offers the theoretical basis for correct time synchronization requirements in bistatic SAR system design.
