摘　　要：With the continuous improvement of Synthetic Aperture Radar(SAR) resolution, interpreting the small targets like aircraft in SAR images becomes possible and turn out to be a hot spot in SAR application research. However, due to the complexity of SAR imaging mechanism, interpreting targets in SAR images is a tough problem. This paper presents a new aircraft interpretation method based on the joint time-frequency analysis and multi-dimensional contrasting of basic structures. Moreover, SAR data acquisition experiment is designed for interpreting the aircraft. Analyzing the experiment data with our method, the result shows that the proposed method largely makes use of the SAR data information. The reasonable results can provide some auxiliary support for the SAR images manual interpretation.With the continuous improvement of Synthetic Aperture Radar （SAR） resolution,interpreting the small targets like aircraft in SAR images becomes possible and turn out to be a hot spot in SAR application research.However,due to the complexity of SAR imaging mechanism,interpreting targets in SAR images is a tough problem.This paper presents a new aircraft interpretation method based on the joint time-frequency analysis and multi-dimensional contrasting of basic structures.Moreover,SAR data acquisition experiment is designed for interpreting the aircraft.Analyzing the experiment data with our method,the result shows that the proposed method largely makes use of the SAR data information.The reasonable results can provide some auxiliary support for the SAR images manual interpretation.
