Embodiment Construction

[0039] based on the following Figure 1 ~ Figure 3 , specifically explain the preferred embodiment of the present invention.

[0040] Relatively speaking, high-resolution HRRP reflects the radial distribution of target scattering points, can represent the structure, center distance, and transformation domain information of the target, and is simpler in terms of acquisition and processing methods. Therefore, target recognition based on HRRP has better Feasibility and practicality. Based on the above, it is necessary to develop a high-resolution one-dimensional range image recognition method for missile-borne weapons ground targets.

[0041] Such as figure 1 As shown, the present invention provides a high-resolution one-dimensional range image recognition method for missile-borne weapons ground targets, which realizes ground target recognition based on multi-dimensional features, queue features, and reliability features, and specifically includes the following steps:

Abstract

The invention provides a missile-borne weapon ground target high-resolution one-dimensional range profile recognition method which comprises the steps of extracting multi-dimensional features of a one-dimensional range profile of a to-be-recognized target, screening the multi-dimensional features of the to-be-recognized target, obtaining a primarily-screened target, analyzing queue features of the primarily-screened target, establishing a suspected target credibility evaluation model according to the multi-dimensional features of the to-be-recognized target and the primarily-screened target, and outputting the target credibility value as a target identification result. According to the method, the problems of strong interference signal, low identification efficiency, difficulty in target accurate guidance and the like in a missile-borne platform complex ground clutter environment are solved.

Description

technical field [0001] The invention relates to the field of radar target detection and recognition, in particular to a high-resolution one-dimensional range image recognition method for missile-borne weapon ground targets. Background technique [0002] The main purpose of the seeker's precise guidance is to accurately detect and track targets from complex background environments and various active and passive interferences. In order to improve the hit rate and effective killing range of guided weapons, the carrier frequency and transmission bandwidth of the active seeker are getting higher and higher, so as to obtain high-resolution images of the detection area, including one-dimensional range profile (High Resolution Range Profile, HRRP) and two-dimensional SAR (Synthetic Aperture Radar) images to achieve the purpose of target information extraction and target recognition. The two-dimensional SAR image uses the relative motion between the target and the radar to obtain de...
