The multi-target cooperative detection information fusion scheme provided by the invention has the advantages of flexible configuration, strong universality and good expandability; and real-time data processing is carried out through the airborne data processing unit, so that the task load of a remote control center is reduced, and the timeliness and safety of the scheme are improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multi-sensor multi-target cooperative detection information fusion method and system. Background technique [0002] With the continuous improvement of the performance of unmanned aircraft and airborne measurement equipment, the measurement mode has changed from the measurement between a single aircraft in the past to the system and system measurement of multiple aircraft formation joint groups. The traditional detection mode of a single unmanned aerial vehicle can no longer meet the needs of tasks such as increasingly complex search and rescue environments. Compared with the traditional single-mode detection task realization method, the cooperative detection fusion method of multiple UAVs has the advantages of robustness, flexibility and scale adaptability. [0003] However, in the existing technology, the completion of cooperative detection tasks is mostly based on the...
