In order to improve the situation that the stor- age mine now could not ascertain the optimum burst point.

The paper deduced the optimal burst angle algorithm and researched an improved Kalman which can increase the estimation precision.

Firstly,the optimal burst angle model and its error analysis model are set up in this paper;then the factors that affect the burst angle scatter and how to estimate the degree of scatter are discussed and analyzed.

Based on the analysis of the national and international development of aimed warhead and the conclusion of its developing direction, this paper establishes a model of missile meeting with target, then gives the analytic expression of optimum detonating delay time, and finally analyzes the result of imitation.

This paper presents a quantitative analysis and a calculation of the mathematic models of the missile in complete movement and the target in its encounter moment by using the information of the control and guide system of ground - to - air missile and the information of the missile in itself, and simultaneously finds out the optimum detonating delay time.

On the basis of this, the paper also discusses the problem how to obtain the optimum detonating azimuth of directional warhead and makes an analysis of th.

In this paper, we first briefly discuss the principle of gimbaled warhead, and deduce the optimum burst range formula.

Based on an analysis of the traditional fuze optimal burst surface (area) and on the condition of dynamic interception, three methods for designing the fuze optimal burst surface(area) are presented.
