利用HRRP对雷达视角敏感这一特点，用隐马尔可夫过程表征多视角雷达回波序列，获得目标距离-方位两维信息。

HMM is used to describe multi-azimuth radar profiles to obtain the distance-azimuth information of radar target through that radar HRRP is sensitive to radar azimuth.

首先给出了双站SAR的回波信号模型，接着分析了方位多普勒信息。

First, the echo signal model of Bistatic SAR is given and then the analysis of the signal in Doppler domain is performed.
