Abstract

PURPOSE:To shorten time required for calculating the quantity of phase shift, by controlling a phase shifter provided on a monopulse synthesizer terminal of a phased array antenna, together with a built-in phase shifter group for an antenna element, and scanning an antenna beam precisely. CONSTITUTION:Scanning angle command signal and a scanning speed command signal are applied to a switching circuit 22 of a beam scanning controller 10 from an information processor. As a result, the circuit 22 provides a calculation start command to a moving extent calculating circuit 11 at every 0.8thetaB, etc. of an antenna beam thetaB, simultaneously phase shifters 191-194 provided on 4 terminals of a monopulse synthesizer 18 are controlled through a moving extent calculating circuit 20 and a moving extent driving circuit 21, and scanning is executed precisely for 0.8thetaB by an antenna array group. During this time, the circuit 11 ends its calculation, a built-in phase shifter group 16 is controlled at every antenna array element by a phase shifter driving circuit 13, and the antenna beam moves its scanning by the 0.8thetaB step. Accordingly, as for the quantity of phase shift of all the phase shifters of the antenna element, it is unnecessary to operate every time even in case of precise scanning, and the time required for calculating the quantity of phase shift is shortened substantially.
