摘　　要：介绍了美国已经使用的加强型主字母飞行终端系统(Enhanced High Alphabet Flight Termination System,EHA-FTS)和即将使用的空间发射飞行终端系统(Space Launch Flight Termination System,SLFTS)安控体制的指令设计原理,通过比较分析,提出了一种将2种安控体制进行兼容设计的方法,这种方法可以利用CPFSK的优点提高系统性能,同时兼容设计的模式能够在不切换地面终端设备模式的情况下,时分复用向多个使用2种体制的目标接收机发送2种体制的安控指令,大大提高了设备的灵活性。这种兼容设计不需要更换硬件平台,只更新内部软件就能实现,既经济适用,又能满足安控所需的保密性、可靠性、低误码率和低虚指令率等性能需求。The design of EHA-FTS which was used and SLFTS which will be used was introduced.Based on comparison and analysis,a compatible system was proposed applicable to the two systems and providing better performance with CPFSK.The ground equipment was so sharp that it could send two type system commands to two type system targets by time division reuse without change over the work mode.The compatible design employs software update instead of hardware,leading to a cost effective approach to satisfy safety remote control on security and reliability and lower BER and lower dummy order ratio and so on.
