ABSTRACT:
A radar system capable of identifying discriminatively multiple reflected waves generated between the radar system and a target (6) to thereby identify discriminatively a first echo indicating a real image from a target (6). The system includes a range finding unit (8) for determining arithmetically distance (R) to the target (6), a distance data processing unit (9) for selecting from plural distance data as obtained a set of distance data indicating the distances which bear an integral multiple relation to one another, a detecting unit (10) for comparing reception amplitude levels (Pr) for individual distance data of data sets with a predetermined threshold level (S) to thereby detect a set of distance data having the reception amplitude levels (Pr) exceeding the threshold level (S), and an identifying unit (11) for identifying discriminatively the distance data based on the first echo from the distance data ascribable to the succeeding multiple reflected waves in the distance data set detected.
