Abstract
Apparatus has a transmitting antenna for radiating transmitting signals over a scanning range in the shape of a fan for a forward direction of ones own vehicle at a constant transmitting cycle, receiving antennas for receiving reflected waves by a target and for outputting receiving signals, spectrum computing means for computing a frequency complex amplitude spectrum from the receiving and transmitting signals, advancing direction computing means for computing an advancing direction of ones own vehicle, advancing direction element extracting means for extracting directional elements corresponding to the advancing direction from the frequency complex amplitude spectrum on the basis of the obtained advancing direction, and for outputting computed result data, distance-azimuth spectrum computing means for computing a distance-azimuth spectrum of ones own vehicle, and target detecting means for detecting the target which exists in a forward direction of ones own vehicle on the basis of the computed distance-azimuth spectrum.
