雷达通信一体化波形分离算法研究

Separation Algorithm Research of Radar-Communication Integrated Waveform

进行了雷达通信一体化波形分离算法的研究,提出了一种新的雷达通信一体化设计方案。该方案通过简单的叠加方式将雷达和通信信号直接合成,避免了由于波形的非正交性带来的影响,在接收端利用盲信号处理的思路进行波形的分离。该方案解决了目前在载机上雷达和通信的不同同时工作的缺陷,并改进了原基于最大信噪比分离算法的一些缺陷,提高了分离的效果。最后,通过仿真结果证明了本文算法的有效性和一体化方案的正确性。

A separation algorithm of radar-communication integrated waveform is researched and a new way of the radar-communication integration is proposed. This way composes the radar signal and the com- munication signal into the integrated waveform by the simple overlay, which overcomes the affect from the waveform＇s nonorthogonality. In the receiving, the integrated waveform by the blind signal processing is separated. Which overcomes the limitation that the radar system and the communication system can realize own function at the same time, solveing the bad effects of the the max-SNR algorithm. At last, the correct- ness of algorithm and the integrated way by some simulation results prove.
