摘要
本文提出了一种MTD滤波器组的优化设计新算法。它可强制滤波器组的频率特性在零频形成零点并使旁瓣面积最小。与Remez多重变换算法相比,在主瓣面积相近的条件下,MTD系统对各种地杂波的平均改善因子提高了约4dB。该优化算法已用于某实际的雷达MTD系统之中并获得了满意的性能。
A novel algorithm for optimal design of filter banks in MTD is presented. It can constrain frequency response of filter banks to form null at zero frequency point and to obtain minimum side lobe area. As contrasted with Remez design algorithm on condition of equal main lobe area, the average improvement factor of MTD system for ground clutter increases by about 4 dB. The optimal design algorithm has been applied to a practical radar MTD system and has provided satisfactory performance.
