Comparison of HRRP-based satellite target identification methods

High Resolution Range Profile is to achieve high-resolution imaging of targets at the radial distance of radar line of sight, which can obtain rich target structure information and is easy to obtain and good in real time. Therefore, characterization of high-resolution one-dimensional distance image and study of target classification and recognition in combination with electromagnetic simulation technology are the key research contents of this paper. To address this idea, a satellite target recognition comparison is proposed to realise the feature extraction by principal component analysis of the 1D distance image data of satellite targets obtained by simulation using FEKO software, and to compare the recognition of different satellite data to verify the recognition effect of satellite targets under different classifiers.
