Design of Anti-Interference Ultra-Wideband Fuze Waveform Based on Chaotic Pulse Position Modulation

In modern warfare, the increasingly complex electromagnetic environment and the enhanced capabilities of intelligent jamming techniques pose a threat to the survival rate of radio fuzes on the battlefield. To improve the anti-jamming performance and thereby enhance the battlefield survivability of radio fuzes, this paper proposes a chaotic pulse position modulation (PPM) method for ultra-wideband (UWB) radio fuzes based on nonlinear mapping. Simulations validate that the proposed method exhibits better autocorrelation characteristics and superior anti-jamming performance compared to unmodulated UWB radio fuzes.
