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.

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。

The four quadrant impulse correction scheme may lead to the losing of thrust and the increasing of miss distance, since this scheme cannot measure the exact target azimuth information.

四象限脉冲修正方案由于没有准确的目标方位信息，会造成脉冲推力损失和脱靶量增大；

Moreover, the azimuth information gotten by the method can also be used as a quantity of state in such models as Kalman filtering of positioning results and further improve its accuracy.

由此估算获得的方位角信息亦能作为一项状态量作用于定位结果的卡尔曼滤波等模型中，进一步提高滤波模型的精度。
