摘要/Abstract

摘要： 针对调频引信抗扫频干扰能力差的问题，建立扫频干扰模型，分析扫频干扰下调频引信失效机理，提出了基于时序及相关检测的调频引信抗扫频干扰方法；综合利用弹目距离信息、双通道时序信息及时间间隔信息作为调频引信输出起爆控制信号的判决条件；仿真验证了算法的可行性，并进行了硬件实现。仿真及实测结果表明，与现有调频引信相比，基于时序及相关检测的调频引信抗扫频干扰方法，有效地提高了调频引信抗扫频干扰能力及引信定距精度，算法复杂度和实时性满足引信要求。

Abstract: Frequency sweeping jamming is a serious threat to frequency modulation (FM) fuze. To improve the anti-frequency sweeping jamming performance of FM fuze, a frequency sweeping jamming mo-del is established, the failure mechanism of FM fuze is analyzed, and an anti-frequency sweeping jamming method based on timing sequence and correlation detection for FM fuze is proposed. The missile-target range information, dual-channel timing sequence information and time interval information are used to control the FM fuze's detonation. The feasibility of the proposed method which is also implemented in hardware is verified through simulation. The simulated and measured results show that the proposed method can be used to improve the anti-frequency sweeping jamming performance and ranging accuracy of FM fuze more effectively compared with the harmonic ranging method, and the complexity and instantaneity of the proposed method can satisfy the fuze's requirement.Key
