Title:
RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/118968
Kind Code:
A1
Abstract:
A stationary object determination processing unit (14) determines whether a distance (R) corresponding to a peak detected by a peak detection processing unit (13) and a Doppler frequency (fd) satisfy the geometric positional relationship of a radar and a stationary object [fd = (2Vaf0/c) / {(R2 - x2)1/2/R} ... Equation (7)]. If the geometric positional relationship is satisfied, the object corresponding to the peak is recognized as a stationary object. Thus, even if the number of peaks detected by the peak detection processing unit (13) increases, an accurate determination of whether an object corresponding to a peak is a stationary object is possible with few computations.
