一种机载阵列天线单站直接定位方法

A Single Moving Observer Direct Location With Airborne Antenna Array

利用当前机载相控雷达自身天线优点,提出了一种机载阵列天线单站直接定位方法。该方法通过对多次观测地面雷达的目标数据进行关联,同时采用空域自适应处理算法实现对地面雷达目标的位置进行解算,该方法可以在不需要获取目标测向参数的前提下直接实现目标无源定位,仿真结果验证了该方法的有效性。

Using the characteristic of airborne antenna array, a single moving observer direct lo- cation is proposed. Combined with multi-time receiving data of ground-based radar signal, and spatial data adaptive processing method, the position of the ground based radar target could be sorted. The target position could be achieved without the parameters of direction of target with this method. The simulation results show validity of the method.
