ABSTRACT:
A radar apparatus installed on a vehicle includes a transmission section, a reception section and a processing section. The transmission section includes at least a transmission antenna, and emits a transmission wave toward a detection area in front of the vehicle. The transmission wave is reflected by a reflector to produce a reflection wave, and the detection area includes a plurality of sub-areas. The reception section includes at least a reception antenna, and receives and detects the reflection wave. The processing section detects a reflector indication data indicative of a reflector attribute based on the detecting result by the reception section, and then determines whether there is the reflector in the detection area, based on the reflector indication data. Also, the processing section manages the reflector indication data over a management area which is wider than the detection area.
