摘要
为适应带宽宽、频率分辨率高以及窄脉冲雷达的应用,采用宽带数字接收机解决上述问题。通过对宽带接收机的原理做了详细介绍,并重点讲解了如何利用宽带数字接收机进行窄脉冲的测频。通过仿真验证了该方法的可行性,并适用于窄脉冲信号的测频。
In order to adapt to the application of wide-bandwidth,high-frequency-resolution and narrow-pulse radar,the broadband digital receiver is presented to solve the problem in this paper.The principle of broadband receiver is introduced, and the method of fre- quency measurement of narrow pulse by the broadband digital receiver is emphasized.The simulation results show that the method is fea- sible and applied to frequency measurement of narrow pulse signal.
