摘要/Abstract

摘要： 为提高复杂战场环境下的无线电引信探测性能和抗干扰性能，设计一种混沌码调相与线性调频复合调制无线电引信发射波形。以模糊函数为工具，理论推导了复合调制波形的模糊函数，定量分析与计算了发射波形分辨性能及抗有源欺骗式干扰性能,并进行了抗干扰性能的实验验证。仿真分析与测试结果表明,混沌码调相与线性调频复合调制信号波形具有更好的分辨性能以及更强的抗有源欺骗式干扰性能。

Abstract: A scheme of modulating the transmitting waveform of radio fuze by chaotic bi-phased code and hybrid linear frequency modulation is proposed to improve the anti-jamming performance of radio fuze in complex battlefield electromagnetic environment. The ambiguity function of the transmitting waveform is derived theoretically, the influence factors of the distance and velocity resolutions are calculated and analyzed quantitatively, and the anti-interception factor is also calculated. The anti-jamming performance of the radio fuze is tested in the ECCM experiments of the fuze prototype and the jamming system. The simulated and experimental results show that the proposed waveform has the better resolution performances and anti-jamming performance compared with the traditional transmitting waveform. Key

Key words: radiofuze, hybridmodulationwaveform, chaoticbi-phasedcodemodulation, linearfrequencymodulation, anti-jammingperformance, ambiguityfunction, resolution, anti-interceptability
