Abstract

The major factors affecting the anti-jamming performance of pseudo-random coded fuzes are analyzed in this paper. Firstly the principle of pseudo-random coded fuzes was introduced. Secondly on this basis, its signal to jamming ratio (SJR) of receiver with Doppler frequency were deduced in the environment of noise FM jamming, then unified representation is put forward. From the SJR its working frequency, pulse width, pseudo-random code period and other factors affect its anti-noise frequency modulation (FM) jamming performance. It provides the important theoretic foundation for the improvement on anti-noise FM jamming performance of pseudo-random coded fuzes and jamming them effectively.

Key words： noise frequency modulation jamming; pseudo-random coded fuzes; Doppler; signal to jamming ratio
