摘要

数据链是战斗力的“倍增器”,军队联合作战的“黏合剂”,是提高作战平台快速反应能力和协同作战能力的关键环节,具有较强的保密性和抗干扰能力。文中以分析数据链中MSK信号抗噪声性能为研究目的,以一跳单脉冲数据链信号的有效驻留时间为仿真对象,对MSK信号频率相干解调方法进行了仿真分析。仿真结果表明,在信噪比高于-15dB时采用频率相干解调方法,可准确实现对MSK信号的解调。

Abstract

The Data link is not only a battle, and joint military operations binder, is to improve the combat platform rapid response capability and the key link of the cooperative engagement capability. It has strong confidentiality and anti-interference ability. Based on the analysis of data link of MSK signal noise resistance for research purposes, choose a jump of single pulse signal data link effective duration as simulation objects, the MSK signal frequency coherent demodulation method have been simulated analysis. Simulation results show that when SNR is higher than 15 dB, the frequency coherent demodulation method can be used to realize the demodulation of MSK signal.

Key words： data link; MSK signal; frequency quadrature modulation; simulation
