<p>A multibeam FM radar system has an FM radar module for transmitting beams of FM signals whose frequencies linearly vary in rising and falling periods, in respective different directions with adjacent ones of the beams overlapping each other, receiving echo signals, and mixing the FM signals and the echo signals into beat signals. The multibeam FM radar system also has a main radar circuit including a central processing unit for producing pairs of frequencies of the beat signals in the rising and falling periods with respect to the beams, and processing the pairs of the frequencies to detect distances up to and/or relative speeds with respect to objects which have produced the echo signals, while reflecting a detected result with respect each of the beams in a detected result with respect an adjacent one of the beams. <IMAGE></p> |
