Abstract: A method used to calculate the radar signal reflected in missile-target encounter trajectory phase was presented, wmch proceeds from the PO and PTD methods. A numerical simulation model was also established. An analysis of results in various miss distance and miss azimuth was made. The effect of miss distance and miss azimuth on fuze actuation was discussed. A comparison between the numerical simulation model and experimental results shows that the method, is good in accuracy and practice in engineering field. It can be used in design of the radio proximity fuze.
