基于改进Jacobi算法的组网雷达目标定位方法研究

Research on Radar Target Location Method based on Improved Jacobi Algorithm

在三维坐标内,存在四个固定的全向天线雷达站形成组网雷达并对一静止目标进行观测,利用经过发射与回波信号混频得到的差拍信号,经过FFT处理得到包含目标距离的状态信息,最后通过改进的Jacobi迭代算法来反解目标估计坐标,并与传统Jacobi迭代算法进行对比,分析了仿真结果,验证改进算法的优越性。

In the three-dimensional coordinates, there are four fixed omnidirectional antenna radar stations forming a networked radar and observing a stationary target. In this paper, the beat signal obtained by mixing the transmitted and echo signals is processed by FFT. The obtained state information including the target distance is finally solved by the improved Jacobi iterative algorithm mentioned in this paper, and compared with the traditional Jacobi iterative algorithm. The simulation results are analyzed and the superiority of the improved algorithm is verified.
