M-FSAD-KD: Full-Link Multi-Granularity Distillation for SAR Object Detection
M-FSAD-KD is proposed, a full-link distillation framework whose neck-stage Fourier-gated alignment transfers low-frequency structural content while preserving target-edge high-frequency content; a joint spatial–channel attention mask, a shallow backbone adapter, and a response-level knowledge distillation (KD) term com...
