一、概述在都普勒体制的雷达上,采用脉间跳频,该雷达就会具有强的抗干扰能力.如果在这个基础上,再加上对于系统内部及外界干扰引起的误差进行自适应修正和实时处理,该雷达就会具有极强的抗干扰能力.用于捷变频雷达的频率合成器,对于间接式合成器,在确保低相噪、高纯度的前提下,达到高速锁相便成了技术难点.在研制高速锁相频率合成器中。为达到20～30μs 的
I. Overview In the Doppler radar system, the use of pulse frequency hopping, the radar will have a strong anti-interference ability.If on this basis, coupled with the system for internal and external interference caused by adaptive error Correction and real-time processing, the radar will have a strong anti-jamming capability.For frequency synthesizer frequency conversion radar, for indirect synthesizer, to ensure low noise, high purity under the premise of high-speed phase-locked Has become a technical difficulty in the development of high-speed phase-locked frequency synthesizer. To reach 20 ~ 30μs
