X 波段快速跳频频率综合器的设计与实现

本文主要以频率合成器在毫米波探测器中的应用为背景，对快速、高稳定、低相噪、小体积频率源进行研究。首先，本文介绍了设计方案及其优点，并且着重分析了环路带宽的选择对频率源建立时间和相位噪声对系统的影响，设计实现了一套模块化的适用于毫米波探测器中的频率源系统，本文使用了乒乓式的锁相环保证了快速的跳频时间和低相位噪声，使用了matlab 分析跳频本振的跳频时序，并且分析振动实验的结果。

Design and Application of X-band Fast Hopping Frequency Synthesizer

In this paper, highly-stable and low phase noise millimeter wave frequency sources areresearched, whichare based on military application, the millimeter wave detector applications. In the paper, we analyze the phase noise in thefrequency source on the system, and design a frequency source system which can be used for millimeter wave detector.This parper uses the ping-pong type of phase-locked loop to ensure a fast frequency hopping time and low phase noise,using matlab to analysis local oscillator frequency hopping sequence and analysis the experimental results of vibration.
