Hongwei Deng · Telecommunication Engineering · 2008
The frequency modulation(FM) radio proximity fuze has the characteristics of simple principle and easy realization.Using digital design,it overcomes the difficulty and weakness of parameter changing in analog design,and has the good practicability.According to the requirements of high reliability and anti-jamming capability for proximity fuze,the PN code modulator scheme and the selecting 7 in 20 decision algorithm are proposed.The project application shows that the digital proximity fuze has high detecting probability,low false and failure probability and better anti-jamming ability.
