中文摘要：

针对距离和角度耦合无法直接获得目标位置信息的问题，提出一种基于MUSIC算法的频率分集阵列雷达目标定位方法。通过改变FDA频率偏置依次发射一接收信号，使距离和角度解耦，再通过MUSIC算法对FDA雷达目标位置进行估计。仿真结果表明，基于MUSIC算法的频率分集阵列雷达目标定位方法在较强噪声环境下具有较好的定位效果。

英文摘要：

The target location cannot be obtained directly from echo due to its inherent coupling range and angle response. This paper presents a means of target location in frequency diverse array radar based on MUSIC algorithm. Range and angle are decoupled by changing frequency offset to transmit and receive signal, and then an estimation is made for the target loca- tion by MUSIC algorithm. The effectiveness of the proposed method is verified by the simulation results, which can get a preferable result in the strong noise environment.
