    摘要： A radar apparatus is provided that can correctly extract the necessary point for a determination related to the safe travel of one's automotive vehicle among objects such as automotive vehicles moving at an angle in front and constructed objects. The radar apparatus of the present invention provides antennas that transmit beams in a plurality of directions and receive the reflected waves from objects as received signals. The objects that generated these reflected waves are detected. In addition, this radar apparatus provides a reflected location detection device that detects the reflected locations that are the generation source of the reflected waves for this plurality of directions, a grouping device that groups each of these detected reflected locations into a group of single or plural reflected locations assuming they belong to the same object, and a device that extracts reflected locations having the shortest distance from the moving body from among these grouped reflected locations to serve as reference points related to the safe travel of this moving body.

    摘要： A multibeam radar system includes a multibeam radar module having n (n is a natural number of at least 3) transmitting/receiving channels for transmitting high-frequency signals and receiving echo signals, and a radar circuit for detecting a distance up to an object which produces the echo signals and/or a relative speed of the object from a relationship between the high-frequency signals and the echo signals in the transmitting/receiving channels. The radar circuit includes a channel controller for selecting sets of m (m is a natural number smaller than n) adjacent transmitting/receiving channels sequentially to transmit the high-frequency signals and receive the echo signals in a high-azimuth-resolution mode. The channel controller may also select the transmitting/receiving channels sequentially one by one to transmit the high-frequency signals and receive the echo signals in a low-azimuth-resolution mode.
