📄 原文摘要

sensing provides comprehensive and effective environment information through complementary signals in data acquisition. As an emerging solution, the multimodal sensing becomes essential and boosts applications in automotive, defence, transportation, life-rescue, and hazard identification, etc. [1]. X-band RADAR exhibits a good balance between free-space loss and directivity, providing bandwidth (BW)dependent range resolution and penetration despite weather conditions in far range. On the other hand, LiDAR features a sub-mm spatial resolution [2], complementarily providing accurate detection in near range. In Fig. 14.2.1, a conceptual system of phased-array RADAR associated with LiDAR (RALDAR) is developed for a radio-laser
