摘　　要：Mark XIIA Mode 5是美军及北约盟军用以提高态势感知能力的新型敌我识别系统。以其为研究对象,首先分析了它所应用的关键技术,如RS纠错编码、软扩频和MSK调制等新技术;其次根据所应用的关键技术对系统进行了模型构建,并以Matlab为仿真平台进行了仿真,得出了询问/应答信号的时域波形及频谱;最后,重点对系统的抗干扰性能进行了分析,分别得出了MSK解调后、解扩后和RS解码后的误码率曲线,可以看出Mark XIIA Mode 5具有很强的抗干扰性能。In order to improve the ability of the Battlefield Situation Awareness,US and NATO armies designed the new IFF system of Mark XIIA Mode 5.Firstly,this paper introduces Mark XIIA Mode 5 IFF system and analyses the key techniques of the system,such as RS encode.Tamed spread spectrum and MSK modulation.Secondly,based on the key techniques of the system the model of the system was designed,and Matlab was regarded as the simulation software platform,the time domain waveform and spectrum of the signal were acquired and analysed.Finally,acquired the bit error rate of the system,the simulation results show that the Mark XIIA-Mode5 system has high performance of anti-jamming.
