This article provides the amplitude variation curves of the radar scattering cross-sectional area under different electrical sizes. Analyzed the calculation method of target scattering characteristics. Explored the target recognition method for multi frequency poles, provided the target impact response curve, and determined the number of target poles using the minimum description length method. At the same time, solved the target poles using the Prony method. Finally, simulation was conducted on high-frequency radar target recognition, and the variation curves of correct recognition rate and rejection with signal-to-noise ratio were provided.
