摘　　要：针对近程高速运动目标,提出了一种基于长基线短距离条件下利用单发多收(SingleInput Multiple-Output,SIMO)雷达系统获得多普勒频率进行目标定位的方法:基于SIMO连续波雷达提取目标的多普勒频率,根据矢量矩阵方程建立最优化函数,采用网格搜索法进行非线性优化处理。仿真结果表明该方法可以得到具有较高精度的定位结果。A target localization algorithm is proposed for the short-range high-speed moving targets, in which the Single-Input Multiple-Output （SIMO） radar system is utilized to obtain the Doppler fre-quencies under the long-baseline and short-range condition. Based on the Doppler frequencies of the targets extracted by the SIMO CW radar, the vector matrix equation is used to establish the opti-mized function and the mesh search method is used for nonlinear optimization. The simulation results demonstrate that the proposed algorithm can obtain the high-precision target localization results.
