信道化接收机的窄脉冲测频问题,与窄脉冲信号的脉宽、功率以及信道滤波器的带宽有关。结合脉冲信号和SAW滤波器的特性,探讨了SAW信道化接收机的窄脉冲测频问题,提出了窄脉冲与宽脉冲分别处理的解决方法,并给出了实测结果。 Narrow pulse frequency measurement of channelized receivers is related to the pulse width, power of the narrow pulse signal and the bandwidth of the channel filter. Combining with the characteristics of pulse signal and SAW filter, the problem of narrow pulse frequency measurement of SAW channelized receiver is discussed. The solutions to the narrow pulse and wide pulse are put forward separately and the measured results are given.
