DETERMINATION OF THE DEPENDENCE OF DOPPLER FREQUENCY ON MISS DISTANCE BETWEEN ARTILLERY SHELL AND TARGET WHEN USING THE RADIO PROXIMITY FUSE UTILIZING THE DOPPLER EFFECT

Abstract

The fuze is the heart of the artillery shells and contains many of the manufacturer's technological secrets. In particular, the radio proximity fuse utilizing the doppler effect has always received special attention from many weapons experts because it ensures the technical requirements and is not too expensive to manufacture. This paper presents the theoretical basis for a mathematical model to determine the dependence of the doppler frequency of the radio proximity fuse utilizing the doppler effect on the miss distance of artillery shells. On that basis, the authors have evaluated the change in the value of Doppler frequency when changing relative velocity and miss distance of artillery shells using Matlab software. The results have shown that when the miss distance of artillery shells increases, the value of doppler frequency also decreases and approaches 0. The Doppler frequency reaches the maximum value when the miss distance of artillery shells is zero. The results obtained can be applied to calculate and design the radio proximity fuse utilizing the doppler effect for artillery shells to destroy aircrafts.
