摘要/Abstract

摘要： 为提高调频引信抗数字射频存储（DRFM）干扰性能，分析了频移DRFM干扰下调频引信失效机理，提出了变调制率调频引信双通道相关检测抗干扰方法。采用相邻周期调制率交替变化使发射信号去周期化，通过快速傅里叶变换提取调频谐波峰值包络并结合双通道瞬时相关检测，实现调频引信的精确定距，抑制频移DRFM干扰。仿真与半实物验证结果表明：同传统调频引信相比较，变调制率调频引信双通道相关检测方法在不增加硬件资源的前提下，可实现精确定距，并显著提高引信抗频移DRFM干扰性能。

Abstract: The failure mechanism of frequency modulation(FM) Doppler fuze under the frequency-shifting digital radio frequency memory (DRFM) jamming is analyzed, and an anti-jamming method of dual channel harmonic correlation detection based on the variable chirp rate transmitting signal is proposed to enhance the anti-jamming performance of FM fuze against the type of DRFM jamming. The chirp rate of the transmitting signal is changed alternately in the same period, the envelope peaks of two channel harmonic signals are extracted based on fast Fourier transform, and then put into an instantaneous correlation detection unit to get the ranging information and depress the jamming signal. The ranging and anti-jamming performances of the proposed method were verified through the hardware-in-the-loop simulation. The simulated results show that the proposed method has better anti-DRFM jamming performance and higher ranging resolution compared to the traditional FM Doppler fuze. Key
