摘　　要：在某MTD雷达信号处理系统中,采用切比雪夫一致逼近法设计MTD滤波器,讨论其硬件实现方法。测试结果表明,各滤波器副瓣在-50dB以下,该MTD系统对地杂波的改善因子达55dB以上,能够达到较好的检测效果。In a MTD radar signal processing system, a MTD filter based on Chebyshev uniform approximation is designed, and its hardware implementing method is discussed. Experiments result shows that side lobe of all filters is lower than -50dB, improvement factor of the MTD system against ground clutter is better than 55dB, which proofs that this MTD system has perfect detection effectiveness.
