FFT-MTD滤波器组优化设计与仿真
Optimized Design and Simulation for FFT-MTD Filter Banks
摘要
Abstract
The method of detecting moving target in radar signal processing system with FFT is introduced. In order to improve the performance of MTD in strong clutter environment, the optimal window for FFT-MTD is discussed. The frequency responses and improving factors of MTD filter banks weighted with 6 kinds of window functions are compared and the optimal window function suitabie for MTD is gained.The simulation result indicates that the MTD performance is improved with the optimized design.关键词
