Automotive mmWave Spinning Radar Place Recognition with Spatially Gated Feature-Correlation Representation
SGCA-Net is proposed, a spinning radar place recognition framework that combines rotation-robust feature extraction with Spatially Gated Correlation Aggregation (SGCA) and consistently outperforms SOTA methods across urban, campus, and open-road environments, while remaining robust to substantial heading variation.
