| 摘 要： | 本文说明了传统雷达通道均衡算法存在的主要问题，并分析了逆傅里叶变换算法均衡性能不理想的原因，基于此提出在逆傅里叶变换之前先对频域抽样点进行优化设计的方法，使得均衡性能得到改善。从运算量看，该方法比直接逆傅里叶变换略有增加，但仍优于加权最小二乘法．Madab仿真实验证明了算法的有效性。

| Abstract: | This paper introduees the main problem of the conventional channel equalization algnrithm in wideband digital array radar, anti analyzes the reason of unsatisfied performance of the inverse Fourier transform algorithm. Then, the optimal design in frequency-domain is proposed, which is adopted before inverse Fourier transform and improves the equalization performance. The improved algorithm also has low computational complexity compared with the weighted least square method. Finally, Matlab simulation shows the effectiveness of the optimal design in Frequencydomain. |
