😍 Fifty Years of SAR ATR: The Road Forward

Jie Zhou, Yongxiang Liu, Li Liu, Weijie Li, Bowen Peng, Yafei Song, Gangyao Kuang, Xiang Li*

This paper provides the first comprehensive review of fifty years of synthetic aperture radar automatic target recognition (SAR ATR) development, tracing its evolution from inception to the present day.

An evolutionary tree of SAR ATR technology from the 1990s to present, organized into four primary branches based on target types: ships, vehicles, aircraft, and other targets. Branch nodes represent landmark methodologies, connecting lines indicate technological inheritance and innovation, while cross-branch linkages signal the emergence of generalizable models.
