<p>PROBLEM TO BE SOLVED: To improve detecting capacity without causing the degradation of a data rate and without increasing the scale of hardware. SOLUTION: In the case of increasing detecting capacity, a search beam pulse width control part 13 of a beam control device 1 processes information from a search beam scan data storage part 14, quadruples the pulse width of frequency corresponding to a certain angle of elevation, for instance, to increase the detecting capacity of that area four times, changes data received from the search beam scan data storage part 14 so as to transmit this angle of elevation separately from the other angle of elevation beam-formed at the same time as this angle of elevation with normal search beam, and outputs the data to a beam scan data originating part 12. The beam scan data originating part 12 sends out the data, received from the search beam pulse width control part 13, to an antenna device 2 and a transmitting device 3.</p> |
