摘要
本文介绍了一种利用现有机载模拟通信设备进行数字通信的高性能机载报警系统。文中,着重论述了该系统在编码和解码技术方面,提高报警信号的抗干扰性、保密性、防止误码以及提高传输距离等关键技术;较详细地介绍了系统的工作原理及调制解调电路的特点。
This paper introdties a high performance airborne warning system which conducts digital com-munication by an available airborne analog communication device. It emphasizes the coding and decodingtechniques and some other key techniques such as improving the resistance to the disturbances of warningsignals,improving the secvecy of warning signals,preventing error-code and increasing the transmissiondistance etc,In addition this paper also presents the operating principles of the system and the characters ofmodulating and demodulating circuit in ditail.
