摘要
针对合成孔径雷达(Synthetic Aperture Radar,SAR)系统性能评价的需求,提出了对SAR原始数据进行分析的一些方法和指标。这些方法和指标包括原始信号的幅值大小对脉冲压缩的影响、各次误差对SAR信号频谱的影响、距离向频谱和方位向频谱的分析等。这些方法和指标既可以帮助检测和调试SAR系统,又可以为后面的成像等各项工作做好准备。这些方法已经应用到实践中,并取得良好的效果。
For the synthetic aperture radar（SAR） evaluation of system performance requirements,some methods and regulations to analyze the raw data of SAR are introduced,which include the checking method of the effect of amplitude for pulse compression,the impact of all kinds of errors on the SAR spectrum,the analysis for the range spectrum analysis and azimuth spectrum,and so on.These methods and regulations can help to detect and debug the SAR system,and prepare for the following imaging work,which has been applied to the debugging and worked out well in the practice.
