摘　　要：由数字射频存储技术发展而产生的许多DRFM干扰,对相参体制的雷达产生了严重的威胁。以DRFM的原理分析为基础,通过分析其局限性找到对抗思路,并结合前人的研究,基于组合波形的思想,以低截获和参数捷变为设计准则,提出了一种脉内非线性调频脉间极化编码的雷达发射波形设计方法,通过仿真验证了该方法的有效性。With the development of DRFM,many DRFM jammings have posed a serious threat to the radar of phase-coherent system.Based on the principle analysis of DRFM,this paper introduces the counter measures by analyzing its limitations.Combined with previous research,based on the idea of combination wave,form with a low interception and parameter agility as the design criteria,a NLFM in pulse non-linear and polarization coding among pulses signal is proposed,and the method is validated by simulation.
