摘　　要：针对软件化雷达可重构的需求,本文提出一种资源复用的时域脉压方法,该方法通过复用FPGA的资源,重构滤波器系数和配置参数,同时调整数据流结构,可实现不同波形的脉压。在不增加系统资源的条件下,本方法可满足多波形的脉压需求。仿真结果表明了该方法的有效性。Software reconfiguration is an important requirement for software radar.An approach for pulse compression based on multiplexing resources was presented in this paper.The method can realize pulse compression of different waveforms by multiplexing resources of FPGA,in which filter coefficients and configuration parameters were reconstructed;meanwhile,data stream structure was also adjusted.The proposed approach can achieve the pulse compression of multiple waveforms without increasing the system resources.The computer simulation verified the efficiency of the technique.
