METHOD FOR DETERMINATION OF MISS IN FIRE BY BURST BY TRACER ANTIAIRCRAFT SHELLS

摘要

FIELD: measurement of experimental characteristics of rocket-gun armament, applicable in fire by burst by tracer antiaircraft shells. SUBSTANCE: target is launched in the direction of one photogoniometer station, fire by burst by tracer shells against target is conducted from a firing gun located near the second photogoniometer station, and the burst miss is determined from dependence: , where, &Dgr;ε(t_n) - average angular position in vertical plane of all shells in a burst relative to the target at time moment t_n, &Dgr;β(t_n) - average angular position in the horizontal plane of all shells in a burst relative to the target at time moment t_n, ε_i2(t_n)-angular co-ordinate of the i-shell in the vertical plane at time moment t_n measured by the second goniometer station, β_i2(t_n)-angular coordinate of the target in the horizontal plane at time moment t_n measured by the second goniometer station, ε_м2(t_n)- angular coordinate of the target in the vertical plane at time moment t_n, β_м2(t_n)-angular coordinate of the target in the horizontal plane at time moment t_n measured by the second goniometer station, n-number of shells in a burst, t_n - time of approach of shells to the target path corresponding to the value, at which , where β_i1(t_n)-angular co-ordinate of the i-shell in the horizontal plane at time moment t_n measured by the first goniometer station, β_м1(t_n)-angular co-ordinate of the target in the horizontal plane at time moment t_n measured by the first goniometer station. EFFECT: enhanced accuracy of determination of miss in fire by tracer shells by direction finding method. 2 dwg
