研究了现代全相参体制脉冲压缩雷达所要求产生的相参的调频脉冲。为此设计了基于锁相环的调频脉冲发生器，其结构包括锁相环路，扫频控制模块和幅度加权模块。在一定的扫频波形下，选取合适的环路参数。基于锁相环的调频脉冲发生器可以灵活地更改脉冲参数，不仅可形成线性调频信号，也可形成非线性调频信号。此方案已在某全相参雷达中得到应用，并测量了输出信号的功率谱，测量结果与计算值相当一致。
The phase-modulated FM pulse generated by modern all-phase pulse compression radar is studied. A phase-locked loop-based FM generator is designed for this purpose. Its structure includes a phase-locked loop, a swept-frequency control module and an amplitude-weighted module. In a certain sweep waveform, select the appropriate loop parameters. PLL-based FM generator can flexibly change the pulse parameters, not only can form linear FM signal, but also can form nonlinear FM signal. This scheme has been applied in a total coherent radar, and the power spectrum of the output signal has been measured. The measurement results are in good agreement with the calculated values.
