The Investigation of a Novel Reentry Telemetry System

摘要

With the development of the missile experimental research,the mea-surement bandwidth of super-fast-signal demands more and more (expected up to 100 MHz) in the reentry telemetry.However,the ability of the current PCM-PPK reentry telemetry system is limited.Also the PCM-PPK system is a non-universal system and impedes the improving of the telemetry technology.Based on the analysis of various modulation systems,the PCM-FM modulation system is pro-posed as a novel reentry telemetry system.The principle prototype of PCM-FM reentry telemetry baseband equipment is successfully developed with the code rate range from 10 to 100 Mbit/s.
