Embodiment 1

[0088] As described in step 1, the thrust compliance coefficient r is obtained 1 =1.1430, resistance coefficient of active section r 2 =0.9893, the resistance coefficient of the passive section r 3 =1.0514 coincides with lift coefficient r 4 = 0.9975. On this basis, the maximum sample size is limited to 8000, for launch point latitude (4-56° (northern latitude)), launch point elevation (0-4500m), range (90-300Km), launch direction (0-360°) , target point elevation (-1500-6000m) and drug temperature (-40°C-50°C) to carry out numerical experiment design, respectively use radial basis function as cubic function and quintic function model and radial basis function neural network Model, a surrogate model for the angle of fire and lateral deviation is established. At the same time, in order to test the prediction accuracy of the firing angle and lateral deviation based on the surrogate model, 1000 random test samples were generated by using the Latin square experimental design m...

Abstract

The invention discloses a long-range rocket artillery firing elements calculation method based on a radial basis function agent model, belonging to the technical field of firing table compilation of the long-range rocket artillery. The invention provides three methods for calculating long-range rocket artillery firing elements, that is, models with radial basis functions as a cubic function and a quintic function and a radial basis function neural network model. The method is characterized in that a firing direction and a firing angle are calculated quickly and accurately when longitudes and latitudes of a firing point and a target point, gun-target elevation and powder temperature are known. In the process of calculating the firing elements, the firing direction is modified at first, then, the firing angle is calculated. The method can be used for calculating the long-range rocket artillery firing elements more quickly and accurately with little data, and can be used for rapidly binding long-range rocket artillery firing elements.

Description

technical field [0001] The invention belongs to the technical field of long-range rocket launching table compilation, and relates to a calculation method of long-range rocket launching elements based on a radial basis function proxy model. Background technique [0002] On the one hand, for the calculation of the launch elements of long-range rocket launchers, the six-degree-of-freedom rigid-body ballistic equations is theoretically the most accurate, but in the actual solution, a small step size must be used, and multiple iterations are required. Calculation The amount of calculation is large and time-consuming, which cannot meet the requirements of the calculation progress of long-range rocket launching elements. Therefore, the six-degree-of-freedom rigid-body ballistic model is rarely used in the calculation of launching elements. On the other hand, the latitude and elevation of the launching point of the long-range rocket launcher, the range, the shooting direction, the e...
