Problems solved by technology

[0002] In modern high-tech systematic wars, the traditional combat method of relying on a single aircraft to fight independently can no longer exert its expected effect. According to the combat methods in recent years, it can be easily seen that offensive aircraft basically In the world, multiple aircraft (types) attack the target in a certain coordinated way. This coordinated attack method is particularly important for high-tech aircraft.

Embodiment Construction

[0061] to combine figure 1 , the present invention is based on the trajectory optimization method of multi-aircraft cooperative operations, and the steps are as follows:

[0062] 1) Collect t s The position coordinates and speed of all our aircraft at all times;

[0063] For example: Take the 4-4 allocation form as an example, the position coordinates of our i-th aircraft are as follows Image 6 shown, the velocity is V i =300m / s, i=1,2,...,4.

[0064] 2) Collect t s The position coordinates and speeds of all target aircraft at all times;

[0065] For example: the position coordinates of the jth target aircraft are as follows Figure 7 As shown, the velocity is v j =300m / s, j=1,2,…,4.

[0066] 3) According to t s Data collected at all times, for target allocation: according to t s The status data of all our aircraft and the status data of all targets are calculated at all times, the remaining flight time of the target is calculated, and the target coordination task a...

Abstract

The invention provides a trajectory optimization method based on multi-aircraft cooperative combat. The trajectory optimization method comprises the following steps of: acquiring position coordinates and speed data of all aircrafts on one part at ts moment, acquiring position coordinates and speed data of all targets at ts moment; computing rest flying time of the target according to the state data of all aircrafts on one part and the state data of all targets at ts moment, obtaining a target cooperative task distribution matrix, performing the target distribution; respectively optimizing trajectory of each aircraft on one part through a dynamic programming method according to the target distribution result at ts moment. The method provided by the invention can be used for performing target distribution on multiple aircrafts in real time according to the current battleground situation in the group cooperative combat of the aircrafts, and for programming the optimal flying trajectory of each aircraft.

Description

technical field [0001] The invention relates to the field of aircraft trajectory optimization technology, especially a trajectory optimization method based on multi-aircraft cooperative operations. Background technique [0002] In modern high-tech systematic wars, the traditional combat method of relying on a single aircraft to fight independently can no longer exert its expected effect. According to the combat methods in recent years, it can be easily seen that offensive aircraft basically In the world, multiple aircraft (types) attack the target in a certain coordinated way. This coordinated attack method is particularly important for high-tech aircraft. Therefore, multi-aircraft cooperative operations are the main combat method in future wars. [0003] As a complex, multi-constrained, and strongly coupled multi-objective optimization and decision-making problem, multi-aircraft collaborative planning can effectively improve the overall combat effectiveness in the battlefi...
