摘要
主字母调制技术是一种新颖的调制方式,非常适合于导弹、运载火箭以及载人和不载人飞船的安全遥控。本文从靶场安控体制的角度来研究实现此技术的基本原理,并从理论方面对主字母调制技术的抗噪性能进行了初步推导。仿真试验实现了全数字化的主字母指令副载波信号的发送和解调,抗噪性能测试的结果与理论分析的结果相一致。
High Alphabet modulation is a new modulation method, which is very suitable for safety remote control aboard missile, launch vehicle, manned or unmanned spacecraft, etc. In this paper, the primary principle is discussed in view of range safety system, moreover, the noise suppression of HA is simply analyzed in theory. In the simulation, the transmission and demodulation of all digital HA safety subcarrier signal is realized. The simulated test result of noise suppression performance of HA is conformed to the theory.
