OBJECT AZIMUTH DETECTION DEVICE, RADAR DEVICE, OBJECT AZIMUTH DETECTION METHOD AND OBJECT AZIMUTH DETECTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an object azimuth detection device that effectively detects an azimuth of an object in an independent multi-beam antenna method.SOLUTION: An object azimuth detection device (for example, a device having an object azimuth detection function provided in a radar device 101) comprises: an antenna part (for example, an antenna part composed of a dielectric lens 1 and a plurality of beam elements 2-1 to 2-M) that forms independent multi-beams; and an azimuth detection part (for example, a function part provided in a signal processing part 8) that detects an azimuth of the object by a maximum likelihood estimation on the basis of signals of the multi-beams reflected upon the object and received by the antenna part.
