Problems solved by technology

[0015] The FUSE system has four functional characteristics: intuitive display, comprehensive identification, efficient load operation, and convenient means of communication. However, there are identification errors caused by association errors, and the association results are expressed in an either-or way. Therefore, the recognition effect still needs to be improved

Embodiment Construction

[0064] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0065] figure 1 A processing flow of a method for comprehensive target recognition using different types of information in the present invention is given, including the following steps:

[0066] Step 1), obtain the motion information and attribute information of the target by multiple types of sensors.

[0067] Among all kinds of sensors, the measurement of the target by the radar system is an exact digital quantity, and all of them are target position and movement information, but because these measurements have some characteristics, the basic probability assignment (BPA) is obtained by using the fuzzy number similarity, and then The fuzzy reasoning of the measurement data obtains the corresponding membership degree, and the basic probability assignment is obtained through the membership degree of the proposition; the photoelectric system compares the targe...

Abstract

The invention discloses a method for carrying out synthetic target recognition through information of different types. The method includes the following steps that (1) movement information and attribute information of a target are obtained through sensors of various types; (2) attribute association based on the DS evidence theory is carried out on the collected attribute information, and track correlation based on target movement information is carried out on the movement information; (3) the degree of association between the attribute information and the movement information of the target is synthesized, and a synthetic recognition result is given out in a probability mode so that later processing of various tasks can use the recognition result according to demands respectively. The accuracy and availability of synthetic target recognition are improved by changing typical synthetic target recognition processing procedures.

Description

technical field [0001] The invention relates to a method for comprehensive target recognition using different types of information in a collaborative environment of manned and unmanned aerial vehicles, and belongs to the technical field of manned and unmanned aerial vehicles. Background technique [0002] In future wars, UAV systems have the characteristics of good stealth performance, strong autonomy, and recyclability, and have been more and more widely used in modern battlefields. However, due to the current ability of the UAV system to perceive the battlefield environment and the ability to automatically understand the environmental situation, it is still unable to completely replace human thinking and judgment, and it is difficult to meet the high-level autonomy and intelligence of the UAV system in a complex combat environment. Therefore, the combat effectiveness of UAVs as a single platform is extremely limited, and it still needs to be mixed with manned aircraft to i...
