Abstract

PURPOSE:To eliminate the machine rotational part and thus realize the full solidification for the electronic scanning system by securing the combination with every correspondence of each radiation element row between the power amplifier and the control unit for the amplification factor. CONSTITUTION:Radiator 6 is included in each row of several radiator rows which are provided cylindrically. Transmitter 7 generates the fixed pulse row by the synchronous signal transmitted from control signal generator 4, and the generated pulse is sent to 1st power amplifier 1. The pulse signal which received the power amplification is divided through power divider 2 and in the number equivalent to the number of the radiation element rows and then supplied to variable power amplifiers 3a and 3b provided in correspondence to power dividers 5a and 5b. The signal output which received the amplitude control by amplifiers 3a and 3b undergoes the power distribution via divider 5 provided to each radiator row in order to obtain the best vertical pattern, and then enters each radiator 6 to be discharged into the space in the form of the electromagnetic energy.
