摘要:
A radar apparatus capable of determining the position of targets at a high accuracy even when plural objects of an identical relative velocity are present in a detection view field of the radar, using signal processing of obtaining an effect which is similar with that of virtually increasing the number of antennas along the moving direction of the radar by determining the change of intensity of reception signals using data in the past in which an identical antenna was positioned at a slightly different place (T1) and data at present (T1+ΔT) as a unit data set.
