Hit Accuracy of Weapon System Test Based on Testing Data of Single Surface-to-air Missile

This paper tests the hit accuracy of weapon system by making full use of testing data information of single surface-to-air missile.It tests the missile speed instantaneous error(system error)variance based on χ2 testing method,and figures out the critical values when two kinds of risk are the same(α=β=0.05,0.1,0.15,0.2,0.25,0.3) based on N(N=7,9,11)track points.This research provides scientific basis for hit accuracy of weapon system test.
