Analysis and circuit design for Doppler digital signal processing using MAX7000A

For the sake of enhancing accuracy Doppler radio fuze,the mathematics models based on target signal is given for the continuous wave Doppler radio fuze. Based on the method of the control of the height of bursts which generally utilize the information from the varying Doppler signal at present, A new procedure which the fuze can identify the distance between projectile and target from the varying Doppler signal pulse width, and there exists a need to provide a near surface burst function to be added to the existing proximity sensor of the fuzz which could provide low height of the bursts, and computer simulation of the fuze is realized by PLD, It is proofed in experiment that the speed of signal processing and system reliability have been improved
