Problems solved by technology

[0005] At present, in order to solve the problem of short-distance top hitting, the improved proportional guidance or over-replenishment methods are generally used in the final stage, while the impact of the program-controlled ballistic form and the final proportional guidance start-up and control conditions on the final hit accuracy and impact is ignored. important influence of angle
[0006] In addition, at present, when domestic researchers design program-controlled trajectories, they mostly use pitch angle program control schemes with time as the parameter variable, and most of the designed program-controlled trajectories are segmented control, with relatively large artificial trial and error factors. Poor adaptability and optimality
When the initial disturbance of the missile is large and the aerodynamic parameters of the missile body fluctuate, it may lead to an increase in the final missed target, and it is difficult to ensure that the angle of impact is the largest under different missile ranges, that is, the performance of the missile is optimal.

Embodiment 1

[0034] figure 1 It is an overall block diagram of the present invention, and the present invention comprises the following steps:

[0035] 1) Firstly, determine a robust ballistic form of image self-seeking short-distance topping anti-tank missile, and its program control section adopts the form of attitude command at line of sight angle q 0 (Constant value to be optimized) As the starting control condition of the end-stage proportional guidance, the coefficient of the end-stage proportional guidance is N; where c and q 0 is the ballistic parameter to be optimized, and q(t) is the line-of-sight angle of the projectile, which can be obtained by measuring the frame angle measured by the seeker system and the attitude gyro on the projectile. The initial launch pitch angle of a missile is

[0036] 2) When the missile is launched, the attitude of the missile body is usually subject to an initial disturbance ω z0 , define the disturbance ω z0 When it is a positive maximum va...

Abstract

The invention relates to a trajectory design and optimization method, in particular to a method for robust trajectory design and parameter optimization of short-distance topping anti-tank missiles, and belongs to the technical field of missile trajectory design. A self-seeking short-distance topping anti-tank missile robust ballistic design and optimization method of the present invention solves the optimal problem of the short-distance topping performance of the image self-seeking anti-tank missile, and then the present invention can be used under constraint conditions And from the initial disturbance situation, a robust ballistic form of image self-seeking short-distance topping anti-tank missile is determined, and the program control section adopts the attitude command form θ c = θ 0 -cq; at line of sight angle q 0 As the starting control condition of the final proportional guidance; the coefficient of the final proportional guidance is N. The ballistic designed by this method is not only robust and practical, but also has near-optimal performance, and can realize dive attack and precise strike at a relatively short target distance. The present invention can be widely used in the ballistic design of self-seeking anti-tank missiles Among them, it has important military application prospects.

Description

technical field [0001] The invention relates to a trajectory design and optimization method, in particular to a method for robust trajectory design and parameter optimization of short-distance topping anti-tank missiles, and belongs to the technical field of missile trajectory design. Background technique [0002] The self-seeking anti-tank missiles that "do nothing" are an important development direction of precision guided weapons in the future. The improvement of the performance of main battle tanks makes the power of traditional anti-tank missiles that directly aim at the front armor of tanks no longer suitable for modern operations. In order to meet the needs of anti-tank guided missiles, topping guidance has become the main attack mode to improve the combat effectiveness of anti-tank missile weapon systems. The so-called top hit guidance means that the missile hits the top armor of the tank with a larger angle of attack and a smaller amount of miss. For self-seeking a...
