Document Type and Number:
Japanese Patent JP2002168942
Kind Code:
A
Abstract:
To provide an antenna unit for a radar of strong directivity capable of limiting a detection area to a desired range without depending on a reflection level of a target.
This antenna unit is provided with antenna elements 4, and a control part 7 for changing an electric power supply level to the antenna elements and a phase. The power supply level to the antenna elements 4 and the phase are controlled by the control part 7 to form the directivity of the array antenna into a rectangular shape.
