CIC滤波器在连续波测速雷达数字基带软件中的仿真与应用
Simulation and Application of CIC Filter in Digital Baseband Software of Continuous Wave Speed Radar
摘要
Abstract
This paper analyzes the theory of decimation filtering and designs a CIC filter suitable for hardware implementation in continuous wave speed radar based on the principle of CIC filte-ring.Using various tools,both a conventional FIR filter and a CIC filter are designed to compare their decimation filtering effects.It can be seen from the output spectrum that,with the same e-quivalent impulse response length,the CIC filter is more efficient than the ordinary FIR filter,which can save computation and achieve better filtering performance.关键词
