The widespread adoption of radar technology in diverse sensing applications, ranging from traffic monitoring over advanced driver assistance systems to healthcare analytics, necessitates robust methods for data synchronization. Although combining radar data with supplementary video or audio recordings enriches scientific analysis, achieving precise synchronization across these systems with varying latencies still can be a challenge. To resolve this synchronization dilemma, we introduce a novel solution: a clapperboard integrated with a corner reflector. Our method is rigorously evaluated, demonstrating its effectiveness in ensuring accurate time-alignment between radar and auxiliary video and audio streams.
