多调制指数连续相位调制体制——军用遥测体制的新发展

Multi-h Continuous Phase Modulation System——A New Progress for Range Telemetry

近年来,美国军方致力于发展新的遥测体制,取代沿用了数十年的PCM/FM体制,以适应迅速扩大的军用遥测传输容量的需求。在简要说明这一发展概况之后,介绍这一发展工作第二个目标的多调制指数连续相位调制体制的基本概念、原理、检测方法、技术指标和基本性能。最后,对这一体制的发展作了简单评述。

With telemetry data rates increasing rapidly,some range telemetry organizations of USA have been investigating new modulation systems in stead of PCM/FM,which is used for several decades.The multi-h continuous phase modulation system is defined as the Tier Ⅱ of the new systems. After an overview of the investigation is briefly presented,the elementary conception,principle and characteristics of the CPM system is explained.Finally,the development of the system is reviewed simply.
