摘要
针对雷达侦察接收机带宽较大,处理速度成为后续数字信号处理的瓶颈,提出一种基于多相结构的宽带数字信道化接收机设计方案,通过信道化降低后续信号处理速度,提高信号的频率分辨率并节省硬件资源。模块仿真测试结果表明该方案可行且实用。
Aiming at the large bandwith of the radar receiver,the processing speed is the botfleneckofdigital signal processing.A design method for wideband digital channelized receiver based on poly-phase structure is proposed,the follow-up signal processing speed is reduced by channelizaiton, signal frequency resolution is improved and the hardware resources are saved. The results of simulation and test of modules prove the design is feasible and practical.
