【摘要】 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。通过计算机仿真结果表明,该方法具有较高的定位精度与较快的收敛速度,可以有效实现对目标的三维定位。更多还原

【Abstract】 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.A solution for the initial value is given and can not only avoid divergence but also accelerate the velocity of result convergence.The simulation results show that the algorithm has high accuracy and fast convergence speed,and can realize three-dimension target location effectively.更多还原
