摘　　要：分析了对美军先进的作战指挥数据链Link16进行欺骗式干扰的可行性。以此为目的,重点分析了JTIDS侦察装备频移载波相干MSK解调原理,通过Matlab仿真实现JTIDS信号的发射与接收过程,最后统计相干解调后不同信噪比下信息码元的误码率,得到该方法的解调性能,为形成欺骗式干扰打下基础。The feasibility of implementing deception jamming for Link16 of U.S. forces is analysed. The princi- ple of frequency shift carrier coherent MSK demodulation of JTIDS surveillance equipment is emphatically analysed. The transmission and receiving of JTIDS signals is simulated with Matlab, and according to the statistical information of symbol error rate under different SNR after demodulation, the demodulation performance of this method is obtained, which lays the foundation for deception jamming.
