Randomized trial demonstrates improved image quality in SAR applications, indicating enhanced diversity control.

The aim is to enhance the diversity and realism of synthetic SAR image generation using a novel model.
Proposed CG-DDPM model incorporates category labels for better diversity control.
Evaluated on the MSTAR dataset and a newly constructed civilian vehicle dataset.
Image quality assessed using Fréchet Inception Distance and Inception Score metrics.
DDPM shows a 12% increase in Peak Signal-to-Noise Ratio compared to other models.
Achieves a 15% higher Inception Score than competing generative models on the MSTAR dataset.
Vision Transformer classifier trained on generated images achieves 98.32% accuracy on MSTAR dataset.
