PriSAR: 3D Geometric-Prior-Guided Diffusion for Parameter-Controlled SAR Image Generation
Fan Zhang, Xuanting Wu, Fei Ma +2
Synthetic aperture radar (SAR) image generation can mitigate data scarcity, but controllablegeneration under sparse observation angles remains difficult. Recent SAR generative stud…
Cross-Sensor SAR Data Generation Using Diffusion Models and Feature Migration
Xuanting Wu, Fan Zhang, Fei Ma +2
Different synthetic aperture radar (SAR) sensors vary significantly in resolution, polarization modes, and frequency bands, making it difficult to directly apply existing models to…
GeoDiff-SAR II: 3D-Driven Foundation Diffusion Models for SAR Generation via Decoupled Control
Xuanting Wu, Fan Zhang, Fei Ma +4
Existing Synthetic Aperture Radar (SAR) image generation methods still lack reliable controllability over key imaging parameters, particularly azimuth angle, depression angle, and…
GeoDiff-SAR: A Geometric Prior Guided Diffusion Model for SAR Image Generation
