正交幅度调制(QAM)在高能爆炸无线电遥测系统中的应用

Application of QAM in the High Explosive Radio Telemetry Project

正交幅度调制 (QAM)是一种多进制振幅相位联合键控技术 ,可以解决高能爆炸的遥测问题。美国洛斯阿拉莫斯国家实验室正在研究开发的高能爆炸无线电遥测系统 ,采用 16进制正交幅度调制 16 QAM技术 ,其频带利用率高 ,信息传输速率高 ,分辩率达到 10 ns级 ,测量容量为6 4路。文中介绍利用正交幅度调制技术的遥测系统的硬件组成。

A overview of a High Explosive Radio Telemetry(HERT)system is presented in this paper.This telemetry system is designed to measure the initial performance of an explosive package under flight environment conditions,transmitting data from up to 64 sensors.It features high speed,accurate time resolution(10ns)and has the ability to complete transmission of data before the system is destroyed by the explosion.
