Optimization Design of Anti-Jamming Channel Range Gate of Pulse Doppler Fuze

In order to further improve the starl-up performance of fuze when missile attacks low-alti- tude target in the sea clutter background, the location of fuzeļ¼‡ s anti-jamming channel range gate is selected by optimizing, the ground and sea clutters are analyzed and calculated by mathematical modeling and numerical simulation. The verification is carried out by a low-altitude flying test. The results show that the sea clutter signal decreases significantly, and the start-up performance of fuze improves obviously after optimizing. This provides a certain theoretical basis for analyzing the start-up performance of pulse Doppler fuze.
