要約(英語): Automotive UWB radar has recently attracted significant attention which increases the driver's safety and convenience. It is required to detect the object in low visibility and to detect the object hidden behind the blind spot during parking or lane change by measuring the distance and angle object around the vehicle. Therefore, a two-dimensional position estimation method based on 2D-MUSIC (Multiple Signal Classification) method is proposed to estimate the position of some targets. However, it requires correlation suppression processing in multi-path environments. In addition, if the number of arrival waves is larger than the number of received antenna elements, separation of arrival waves becomes difficult. In this paper, therefore, MIMO (Multi Input Multi Output) Virtual Array is used to increase the number of receive antenna elements. Correlation suppression of the coherent waves is also performed using the spatial smoothing processing in the frequency domain. We conducted measurements and investigated the usefulness for various scenarios.
