Abstract: With the development of urbanization and human activities, the urban building environment is becoming more and more complex. The target detection and information perception of urban building sheltered space is important for civil and other applications. The traditional methods for detection and localization of targets cannot work effectively because of the obstruction and the fading and multiple paths caused by the buildings. Therefore, the ultra-wideband through-the-wall radar is utilized for the penetrating detection and information perception of urban building. In this talk, the building structure reconstruction, the indoor target imaging and the human behavior recognition are mainly investigated and discussed. Firstly, the building structure is reconstructed by the joint estimation of wall and corners based on the attribute scattering center model with semantics constraints. In addition, the generative adversarial networks are explored to improve the resolution of target image by the fusion of image information from radar and camera. Finally, a lightweight multi-scale neural network is designed to extract macro and micro-Doppler features for indoor human activity recognition. These works will improve the performance of target detection and information perception of urban buildings, which will provide technical and information supports for the development, construction and security of city.
