The model of motive system is made in the light of measurements of target bearings, elevation and frequency by passive sonar.
首先以无源声呐对目标的方位角、俯仰角和频率测量为依据，建立动态系统模型。

Based on the temporal-spatial sequential Maximum Likelihood (ML) algorithm, a new algorithm for estimating the elevation Angle of a target in radar low-angle tracking environment is presented.
在时空级联最大似然算法的基础上，本文结合雷达低角跟踪的特点，提出一种新的目标仰角估计算法。

During radar tracking target in low elevation, the measuring error of tracked target was removed or reduced with array antenna beam forming technique that can reduce the multi-path error.
