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.
