The extraction and use of typical aerial targets information for the naval ordnance proximity fuze

Based on actual Doppler signals measured from the process of approach of pills and targets and theoretical deduction, characteristics on the echoes of the typical aerial targets are analyzed. The article then studies the extraction and use of the typical aerial targets Doppler information for the naval ordnance proximity fuse. The design ideas of the signal processing circuit of naval ordnance fuze are presented. Full use is made of the altitude and frequency information of the echoes, and the ability of information processing and anti-jamming is brought to a new level.
