摘　　要：以双站SAR系统的空间几何布局为出发点,分析了双站SAR系统的距离史和距离变化率史,并将其与单站系统进行了比较,说明了它的特殊性和复杂性。通过对双站SAR系统的点目标信号的分析,推导出它的相位变化史及其特性,为双站SAR系统信号处理的研究提供了理论依据。Firstly, the model about space geometry layout of bi-static SAR system is given, its range history and range change rate history are analyzed as well. Comparison of the result to the mono-static SAR demonstrates its specialty and complexity. Lastly, the point target signal of bi-static SAR system is analyzed, and its phase variation history and its character are derived, which provide the theory reference for the signal processing research of bi-static SAR system.
