Research Article PLANETARY SCIENCE Science Advances 1 Jan 2025 Vol 11, Issue 1 INTRODUCTION Orbital and in situ observation magnetic data indicate that the present-day Moon does not have a global magnetic field; nonetheless, large-scale crustal magnetization with maximum local magnetic anomalies at the lunar surface reaching hundreds of nanoteslas suggests the presence of a strong magnetic field in the past (1, 2) (Fig. 1).

1. Introduction With the rapid acceleration of urbanization, traffic safety issues are becoming increasingly prominent. Pedestrian detection, a crucial technology in intelligent transport systems, holds significant research importance and practical value. Effective pedestrian detection algorithms can identify and locate pedestrians in real-time traffic scenarios, thus providing essential data support for intelligent driving [1], automated parking [2], and monitoring systems [3].
