摘要
介绍微波扫频技术发展经历的3个阶段,即从开环式扫频、锁滚式扫频发展到锁相扫频,分析比较各种扫频方案的内在机理和优缺点,阐述了微波合成扫源中锁相扫频的工程化实现方法与设计要点。
This paper introduces three schemes of sweeping during the development of the microwave sweeping technology, such as open-loop sweeping, roll-lock sweeping, phase-lock sweeping, etc. The intrinsic elements and the characteristic of each scheme is analyzed, and how to realize and optimize the last scheme in the microwave synthesized sweepers is also described.
