调制域分析是结合时域分析中的时间参量和频域分析中的频率参量,表征信号频率随时间变化的关系,以说明信号的调制域特性,它通过无死区计数可以快速分析出被测信号的微小频率变化,高达百万次每秒的测量速度,能够测量、分析瞬态信号频率、相位随时间变化关系。特别是随着宽带分频器件的发展,通过分频降频处理方法,调制域分析技术可实现10GHz瞬态测频带宽,满足宽带跳变信号的测试需求,可广泛应用于宽带捷变频雷达、跳频通信等武器装备中用于宽带频率跳变信号测试。
Modulation domain analysis is the combination of time-domain analysis of time parameters and frequency domain analysis of the frequency parameters, signal frequency characteristics of the relationship between changes over time to illustrate the modulation characteristics of the signal, it can be no dead zone count can be quickly analyzed by the measured Small changes in signal frequency, up to millions of times per second measurement speed, can measure and analyze the transient signal frequency, phase changes with time. Especially with the development of wideband frequency division devices, the modulation domain analysis technology can realize the 10GHz transient frequency measurement bandwidth through frequency division down-conversion processing to meet the testing requirements of broadband hopping signals and can be widely applied to broadband agile frequency radar, Frequency hopping communications and other weapons and equipment for broadband frequency hopping signal test.
