摘要：
This study evaluates and quantifies the atmospheric phase screen (APS) effects in a 79 GHz multi-input multi-output (MIMO) radar system. In addition to the 79 GHz radar measurement, the 17 GHz ground-based synthetic aperture radar (GB-SAR) measurement was performed simultaneously for comparison. We conducted a 24-hours continuous experiment in an outdoor environment with a maximum range distance of 130m. We deployed nine stationary corner reflectors (CR) to investigate the sensitivity to atmospheric disturbance. Our analysis revealed that the effect of APS in 79 GHz radar was more pronounced than in 17 GHz GB-SAR. Nonetheless, appropriate APS compensation led to smaller residual APS than 17 GHz radar. The feasibility of using a 79 GHz low-cost small radar system for long-range environmental displacement monitoring would partly be shown in the presented study.
