Target type identification method and system and electronic equipment

Abstract

The invention relates to a target type recognition method and system and electronic equipment, and the method comprises the steps: obtaining the first track information of each information point of ato-be-recognized track, obtaining the importance of each feature, and obtaining a preset number of target features according to the descending order; obtaining data corresponding to a preset number oftarget features from the first track information of each information point of the to-be-identified track, and obtaining second track information of each information point of the to-be-identified track; and inputting the second track information of each information point of the to-be-identified track into the trained decision tree to obtain a target type corresponding to the to-be-identified track. According to the importance degree of the features, the preset number of target features are selected in sequence in the multiple features and the unimportant features are ignored, and then the dimension reduction is performed on the first track information to obtain the second track information, so the operand is reduced, the target type corresponding to the to-be-tracked information can be timely and accurately determined, and the cost of the low-altitude monitoring radar is not increased.

Description

technical field [0001] The present invention relates to the technical field of target type identification of flight tracks, in particular to a target type identification method, system and electronic equipment. Background technique [0002] At present, radar generally uses the following two technical means to identify target types such as vehicles, birds, drones, and civil aviation, specifically: [0003] 1) Classify the signals detected by the radar through the micro-motion characteristics of the signal processing domain to achieve the purpose of identifying the target type, but the micro-motion characteristics of the signal processing domain have higher requirements for the signals collected by the radar. Radar is difficult to meet the requirements and the cost is high; [0004] 2) Classify the track information monitored by the radar to achieve the purpose of identifying the target type. Although the signal requirements for the track information collected by the radar ar...

Problems solved by technology

[0003] 1) Classify the signals detected by the radar through the micro-motion characteristics of the signal processing domain to achieve the purpose of identifying the target type, but the micro-motion characteristics of the signal processing domain have higher requirements for the signals collected by the radar. Radar is difficult to meet the requirements and the cost is high;

[0004] 2) Classify the track information monitored by the radar to achieve the purpose of identifying the target type. Although the signal requirements for the track information collected by the radar are relatively low, the track information collected by the radar is very rich. For example, the track information includes position information, motion information, radar cross-sectional area, etc., resulting in a large amount of calculation, and the target type corresponding to the track information cannot be obtained in time
