用于ISAR一维成象的雷达信号采集系统

Radar Signal Sampling System Used for OneDemensional Inverse Synthetic Aperture Radar

依据采样信号特征和要求，叙述了采集信号的方法，并给出了一种避免采样信号饱和，提高采样质量的信号采集设计方案。文中还讨论了信号采集启动方式、存储器容量的选取以及系统误差校正的方法。

According to sampling signal characteristics and requirements, the method of radar signal sampling is introduced. In order to avoid sampling signal saturation and to improve sampling signal quality, a kind of design of radar signal sampling is also provided, method of signal sampling trigger and RAM capacity consideration and system error correction are discussed.
