For the accuracy of range information is higher than that of azimuth information received by networking radar system,three-dimension target location based on range only is proposed by using the linear least square iteration algorithm.
在雷达组网背景下,针对雷达测量距离精度较高,测量方位精度较低的特点,利用组网雷达的距离信息,采用线性最小二乘迭代算法对目标三维定位进行了分析,并就迭代初始值给出了一种解决方法,不仅可以避免迭代结果的发散,而且可以提高线性最小二乘迭代算法的收敛速度。
