Abstract
To improve the anti-jamming ability of the continuous-wave Doppler radio fuze, based on the difference between the characteristics of echoes from a typical aerial target and those of the jamming wave, a kind of signal processing circuit is described, that is centered on a microprocessor unit and utilizes the frequency information of the echoes to control the proximity distance between the target and the projectile. Results of computer simulation and experimental tests show that the circuit can successfully control the proximity distance and has a better jamming resistance against the interference from two kinds of jammers.
