Title:
RADAR APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/002221
Kind Code:
A1
Abstract:
A radar apparatus includes a transmitting portion, a receiving portion, and an estimation portion. The transmitting portion (16) includes transmitter elements (30) emitting a transmitting signal as a radar wave toward an object. The receiving portion (20) includes receiver elements (34) receiving a reflection signal. The estimation portion generates a virtual receiving array including virtual receiver elements whose number corresponds to a total number of receiver elements (34) multiplied by a total number of transmitter elements (30). The estimation portion divides the virtual receiving array into identical sub-arrays. The estimation portion generates covariance matrix data for each of the sub-arrays. The estimation portion averages the covariance matrix data and spatially smooths the reflection signal. The estimation portion resolves the direct reflection signal from the object and the multipath reflection signal. The estimation portion determines the direction of the object.
