Embodiment
[0074] In order to verify the validity of the scheme of the present invention, the following simulation experiment is carried out by taking the straight line variable acceleration route as an example, and the route parameters are as follows:
[0075] x 0 =-3000m; y 0 =800m; h 0 =500m;
[0076] vx 0 =100m / s; vy 0 = 80m / s; vh 0 = 0m / s;
[0077] ax 0 =10m / s 2 ; ay 0 =0m / s 2 ; ah 0 =0m / s 2 ;
[0078] where (x 0 ,y 0 ,h 0 ) is the initial position of the target, (vx 0 ,vy 0 ,vh 0 ) is the initial velocity of the target, (ax 0 ,ay 0 ,ah 0 ) is the initial acceleration of the target, and no change is indicated, indicating that the target has been moving at this speed and acceleration since then.
[0079] Three models are used to predict the off-target amount, and the simulation results are as follows Figure 6-8 As shown, the statistical characteristics of prediction error are shown in Table 1.

The invention discloses a large closed-loop amending control method for an antiaircraft gun fire control system. The method comprises the following step: acquiring target location information, estimating a motion parameter thereof; establishing a target motion model, solving a point of impact, and then determining corresponding firing data; performing a projectile firing experiment to acquire missdistance information after the projectile firing; performing model category identification according to the miss distance information, and establishing a miss distance model, predicting the correction by applying Kalman filtering, and performing firing data correction. On the basis of the prior art, the miss distance information identification loop is added, the more appropriate miss distance mathematical model is established, and the firing accuracy of the antiaircraft gun can be improved.
Description
technical field [0001] The invention relates to a weapon system control technology, in particular to a large closed-loop calibration control method for an antiaircraft artillery fire control system. Background technique [0002] All countries in the world attach great importance to air defense and the construction of a strong and modern prevention and control system, and our country is no exception. my country's short-range air defense and anti-missile weapon system is dominated by anti-aircraft guns, supplemented by a mixture of anti-aircraft guns and anti-aircraft missiles. At present, the realization of the large closed-loop is to correct the shooting error by modeling the amount of miss, but in order to reduce the complexity of the system and enhance the real-time performance of the system, it is a simple modeling of the amount of miss as a whole, so that the shooting error of the antiaircraft gun in the shooting Still big, with low accuracy and damage effectiveness. ...
