The system comprises a flight mission range determination module, a flight path model determination module, an instruction correction capability parameter table formation module, a new target point acquisition device, an aircraft flight distance determination module, an instruction correction distance determination module, a target correction distance module, a maximum target correction distance module and a correction judgment module. Under the condition of a simplex instruction correction system, the flightposition estimation error is reduced, and the accuracy of estimating the instruction correction capability of the aircraft is improved; according to the method, the aerial flight position of the aircraft under the multi-constraint condition is adopted, the instruction correction capability of the aircraft is obtained, and wireless instruction correction can be effectively executed.

Description

technical field [0001] The invention relates to an aircraft wireless command correction method and system, and belongs to the technical field of guidance and control. Background technique [0002] When the aircraft using simplex command correction mode strikes time-sensitive targets, it is required to shorten the contact time of the aircraft as much as possible and improve the combat effectiveness of the weapon. However, due to the influence of factors such as target concealment, the target detection ability and capture accuracy will be deteriorated. Therefore, there is a contradiction between target detection accuracy and combat effectiveness. For aircraft using the wireless command correction system, the ground command system only needs to know the initial position of the target and the area where it may be scattered to launch the aircraft. During the flight, the maneuvering elements of the target are further determined and sent to the aircraft through the correction syst...

AI Technical Summary

Problems solved by technology

Since the aircraft adopts the simplex command correction mode, the ground command system cannot obtain the current precise position of the aircraft, so it cannot accurately estimate the command correction capability of the aircraft

[0003] The location of the aircraft is very scattered under different launch environment conditions. If a conservative estimation method is adopted, the estimation of the aircraft's command correction capability will have a large error, and the combat effectiveness of the aircraft cannot be fully utilized.

The existing technology generally uses the initial position of the target, the launch speed, and the launch sector as input constraints to obtain the preset flight trajectory, but the preset flight trajectory is different from the flight trajectory in the actual flight process, resulting in the estimation of the flight trajectory based on the preset flight trajectory. The obtained position information has a large error
