摘要行进间射击不同于静止射击，不但要考虑载体的运动，还要考虑路面谱对载体姿态的影响，并由此影响射击延迟时间和首发命中率。此课题比较符合现在的实际情况，深入研究对武器系统的精度有着重大的意义。9020

Title the analysis of the effectiveness and
efficiency of the shooting-in-moving
Abstract
Shooting-in-moving is different from stationary shooting. Not only the movement of the carrier, but also the influence of road spectrum on the carrier attitude should be considered, which affects shooting delay time and first hit probability.
The main contents of the thesis are as follows:
(1)Research on random response of shooting-in-moving.
This paper presents a solved computation method for non-stationary random response subjected to excitation based on the theory of vehicle dynamics, launch dynamics and random vibration. By this method, The dynamic characteristics and dynamic response of the shooting-in-moving system on random road is also discussed in this article, which will be reference for the design of the system and practical applications.
(2)Calculation of shooting delay time.
The shooting delay time as result of the equipped shooting gate is studied for the weapon system with shooting gate. We calculate the shooting delay time on the basis of random cutthrough theory.
(3)Analysis of first hit probability.
The rate of transition probability matrices is defined by the concept of the transition probability matrix with absorption. The dissertation derivatives the first hit probability calculation formula and discusses the correlation coefficients on the influence of the first hit probability.
Keywords: random response, road spectrum, shooting delay time, first hit probability
