Abstract
To improve the anti-AM jamming performance of FM Doppler fuze, the AM jamming mechanism was quantitatively studied, and the anti-jamming performance of FM Doppler fuze under different AM jamming was quantitatively studied with signal to jamming ratio (SJR) gain as descriptive parameter. The SJR gains of FM Doppler fuze in the environment of sine wave AM jamming, square wave AM jamming and triangle wave AM jamming were deduced in detail and verified by simulation. Quantitative analysis, simulation and experimental results indicate that the total SJR gain of FM Doppler fuze is at 10 dB under AM jamming; anti-AM jamming performance of FM Doppler fuze is not sensitive to the types of AM waves; modulation depth nearly has no effects on the anti-jamming performance of FM Doppler fuze; to a certain extent, reducing Doppler filter bandwidth can improve the anti-jamming performance of FM Doppler fuze system.
