Radar antenna device and method for controlling electric power source thereof

Abstract

A radar antenna device is provided for rotating an antenna unit which successively emits transmission signals. It is configured to reduce the capacity of an electric power source for supplying electric power to a transmission circuit, a drive unit and the like. A radar antenna device is comprised with an antenna unit and a control unit. The antenna unit is driven by a drive unit to rotate and emits successively transmission signals generated by a transmission circuit into an outer space. After electric power is supplied to the drive unit to be driven, the control unit controls the transmission circuit in response to the transmission start signal from the transmission start signal producer so that the electric power for the transmission will be supplied to the transmission circuit.
