Abstract

The invention is suitable for the technical field of radar, and provides a dense multi-target parameter extraction method and device and terminal equipment, and the method comprises the steps: readinga pre-processed to-be-detected image in any distance door; calculating a gray scale gradient maximum value in the to-be-detected image, determining edges of a plurality of targets in the to-be-detected image, binarizing on the to-be-detected image of which the edges of the plurality of targets are determined, and determining a binary image matrix corresponding to the to-be-detected image; determining minimum bounding rectangle data corresponding to each target area according to the binary image matrix; calculating the pixel point with the maximum amplitude in each minimum bounding rectangle data, and taking the pixel point with the maximum amplitude as a mass point corresponding to each target; and determining the time, speed and amplitude data of the target according to each mass point.Therefore, the time, the speed and the amplitude of each target can be effectively extracted, and conversion from digital signals to physical parameters is realized.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a method, device and terminal equipment for extracting dense multi-target parameters. Background technique [0002] Target parameter extraction is the process from echo signal data file to target parameter file, and it is a key step from digital signal to physical parameter. Accurately extracting the time, frequency and amplitude information of projectile particles from the noise-reduced echo data is the key processing step of the whole speed measuring radar system. After constant false alarm processing, the signal-to-noise ratio of the projectile echo signal is greatly improved. Since there are a large number of targets in each range gate, the conventional single-target parameter extraction method is usually in the time domain or frequency domain. One dimension is to judge the existence of the target according to the echo amplitude exceeding a specific threshold, and ...
