Problems solved by technology

Because passive positioning generally cannot obtain the distance information of the radiation source, the traditional passive positioning method usually uses a single observation station to measure the angle of the radiation source, but the positioning accuracy and scope of application of this method are limited
In recent years, the research of using multiple aircraft for passive positioning has begun to rise, mainly including direction finding cross positioning, time difference positioning, direction finding time difference positioning and other methods, but the positioning accuracy of these traditional methods is difficult to meet the needs of precise strikes on the battlefield

Embodiment Construction

[0051] The operational schematic diagram of the cooperative system of the present invention is as follows: figure 1 shown. figure 1 Among them, 1 manned fighter and 4 UAVs constitute a manned / unmanned aerial vehicle cooperative combat system. UAVs are divided into two categories, among which 3 UAVs are used for passive positioning, and u i (1≤i≤3) means, U R For radar drones, M L Indicates that there is a machine. The dotted line represents the formation projection in the plane during UAV observation, which is a circle; the line composed of scattered points represents the UAV observation ray; the dotted line with arrows represents the data link, specifically: three UAVs Summarize target information to u 1 , and the aircraft transmits target information to M in real time L ,M L Positioning acquisition is to release the missile after obtaining the target position. When the missile flies to the middle section, M L Command U R Turn on the fire control radar to guide the m...

Abstract

The invention provides a precise target positioning and striking method based on a manned / unmanned aerial vehicle cooperative combat system. The method comprises firstly determining the constitution and the combat flow of the manned / unmanned aerial vehicle cooperative combat system according to the characteristics of a task, and determining fast and accurate positioning as a researched core issue;then introducing a precise target positioning method based on a observation vector projection point, and establishing a complete optimization models according to the distribution of the projection points; and finally, using an optimization tool to achieve a quick search of the optimal solution. The method clarifies the tasks of various aircrafts in the system, fully utilizes the advantages of system combat on the basis of guaranteeing the safety of the manned aerial vehicle, can fast solve the objective function by using the optimization tool, can meet the requirements of precise positioning,and provides the basis for the battlefield precise target striking of the system.

Description

technical field [0001] The invention belongs to the technical field of manned / unmanned aerial vehicle cooperation, and in particular relates to a precise target positioning and strike method based on a manned / unmanned aerial vehicle cooperative combat system. Background technique [0002] In the battlefield, it is very important to ensure the safety of the pilot in the manned aircraft. Therefore, in recent years, drones have gradually developed into an important air-based weapon platform in modern military warfare due to their advantages of high cost-effectiveness and no casualties. , but subject to the current level of information technology development, the level of intelligence and autonomy of drones is still not high. Therefore, building a manned / unmanned aerial vehicle cooperative combat system will become a more realistic and feasible way of air combat in the future. [0003] The manned / unmanned aerial vehicle cooperative combat system refers to the overall formation ...
