The present invention provides a multi-core and multi-threaded UAV search target method and device, belonging to the field of UAV search and tracking technology, the method includes: loading the target database into the UAV reconnaissance load; when the UAV reaches the target area Finally, use multi-core and multi-thread parallel search, intercept or track radar target; wherein, the acquisition method of the target database is: filter out the characteristic data that can identify the radar target, according to the capacity of the UAV load database, the target radar The feature data is decomposed and grouped to generate the target database. Compared with the traditional method, the radar target database constructed by the present invention has strong pertinence, accurate and fast search and interception of targets, and effectively solves the problem of poor real-time performance in the search and interception of complex radar targets by existing unmanned aerial vehicles.
Description
technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle search and tracking, and more specifically relates to a multi-core and multi-thread unmanned aerial vehicle search target method and device. Background technique [0002] In the information age, the electromagnetic environment is increasingly complex and changeable, which is manifested in the number of radiation sources, the variety of signal sources, the complexity of signal waveforms, the multiple functions of a single radiation source, and the changeable signal style parameters, etc. The load processing detects a large amount of data, and traditional serial computing is difficult to meet the needs of comprehensive and rapid interception and identification of complex targets. [0003] The existing technology has been optimized from the following aspects, such as: pre-preparation of weapons in autonomous attacks, improvement of the search and suppression efficiency of anti-radiati...
