Abstract

The invention discloses a tank armored vehicle acoustic vibration artificial intelligence detection and positioning system, which relates to the technical field of target detection and positioning, and comprises at least three groups of acoustic cross arrays, at least three groups of vibration sensors, an artificial intelligence positioning unit and a signal processing unit; wherein the artificial intelligence positioning unit is connected with the at least three sets of sound cross arrays and the at least three sets of vibration sensors and used for training an RBF neural network through input and expected output according to detection output of the sound cross arrays and the vibration sensors and obtaining a first target position and a second target position according to training results; and the signal processing unit is used for performing weighting calculation on the first target position and the second target position by utilizing a weighting function to obtain the final position of the tank armored vehicle. According to the method, sound detection positioning and vibration detection positioning are combined, the first target position and the second target position are obtained through calculation by means of the RBF neural network, and the detection positioning test precision of the tank armored vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of target detection and positioning, in particular to an acoustic-vibration artificial intelligence detection and positioning system for tanks and armored vehicles. Background technique [0002] Due to the complex environment on the battlefield, gunshots, artillery sounds, helicopter sounds and other noises are mixed together, which has caused great interference to the sound positioning measurement technology, greatly reducing the positioning accuracy and recognition accuracy, and the battlefield environment is not allowed to use Too complex array detector. [0003] At present, the target positioning methods mainly include: positioning based on beamforming, positioning based on time difference of arrival and positioning based on high-resolution estimation. Due to the complex battlefield environment, it is difficult to guarantee the positioning accuracy of the traditional single positioning method, and even ...
