<p>PURPOSE:To simplify the constitution of a transmitter, by performing three simultaneous beam scannings. CONSTITUTION:In transmission, the exciter 21 of a transmitter 2 is controlled by a timing controller 1 and almost simultaneously generates plural high frequency pulse signals 30 having different frequences. The signals 30 are applied to a change-over device 23 through an amplifier 22 and the components 301-303 of the signals 30 are outputted while successively changed over by timing from the controller 1. The signals 301-303 are supplied to the current supply terminals 41, 42, 43 of an antenna 4 through transmitting and receiving separators 3-1- 3-3 and almost simultaneously emitted to a space. In reception, the reflected signals from an object are simultaneously collected by each beam and transmitted to receivers 5-1-5-3 while demodulated output is sent to a display device 7 through a signal processor 6.</p> |
