仿真结果表明，对于纯方位跟踪问题，U PF不仅解决了扩展卡尔曼滤波器的线性化损失难题，而且与PF等粒子滤波器相比，具有更高的跟踪精度。
The results show that the UPF not only solves the linearized loss problem in the extended Kalman filter, but also is more accurate than the PF in the BOT.
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；
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.
