Abstract:
A radar apparatus installed on a vehicle comprising:a transmission section having at least a transmission antenna, for emitting a transmission wave toward a detection area in front of said vehicle so as to be reflected by a reflector to produce a reflection wave, and said detection area includes a plurality of sub-areas;a reception section having at least a reception antenna, for receiving and detecting said reflection wave;detecting means for detecting reflector indication data indicative of a reflector attribute for every said sub-area for a current detection cycle based on a detecting result by said reception section, for determining whether said detected reflector indication data are correct, by use of said detected reflector indication data, and for determining that said detected reflector indication data are final reflector indication data when said detected reflector indication data are determined to be correct;correcting means for correcting an incorrect part of said detected reflector indication data to a correct reflector indication data to produce said final reflector indication data, when said determining means determines that said part of said detected reflector indication data is not correct; anddetermining means for determining whether there is said reflector in said detection area, based on said final reflector indication data.
