<p>PURPOSE:To reduce the load of a manipulator from the standpoint of working, by a method wherein the angle to be set of a scanning antenna is automatically controlled and corrected corresponding to the admission angle position of an airplane and the like and the angle position is numerically displayed. CONSTITUTION:The reflected signal from an airplane 1 outputted from a height scanning antenna 7 is supplied to a height and angle position detector 9 and an indicator 14 through a receiver 13 while the height and angle signal from the antenna 7 is also supplied to the detector 9 and the indicator 4. The detector 9 refers to both signals to generate the height and angle position signal of the aeroplane 1 and sends said signal to an azimuth scanning antenna height and angle driver 12 and the indicator for the sake of the control of an azimuth scanning antenna 8 while the height and angle of the aeroplane 1 corresponding to the antenna 8 is numerically displayed by the indicator 14. In the driver 12, the antenna 8 is driven and controlled on the basis of the output of the detector 9 and the angle to be set in the height and angle of the antenna 8 is corrected so as to be fitted to the admission angle position of the airplane 1.</p> |
