FIR窄带滤波器组在现代雷达中的实现和优化方法

摘要

提出了一种动目标检测滤波器组在FPGA中的设计方法,给出了FIR滤波器组的设计原则和滤波器的设计步骤,并给出一组滤波器的频响曲线,运用该滤波器对某雷达回波数据进行了处理。实现了滤波器组在FPGA中的应用,并就实现过程作出了优化。%A method of the MTD fiher bank in the FPGA is designed and presented with the principle, procedures and frequency response curves of the FIR filter bank given. The echo data of a radar are processed through the filters. The application of the filter bank in the FPGA is implemented, and the implementation process is optimized.
