Abstract: For the sake of improving effectiveness in fuze-warhead,computer simulation of the pulse-Doppler radio fuze is discussed.On the basis of the proposed general conception,a basic simulation scheme for fuze-warhead matching is given and the basic simulation models including emitting,reception and signal processing are established.A procedure with which the fuze can identify the distance between projectile and target and determine the optimum delay the according to information from the varying Doppler signal amplitude,are suggested.
