PURPOSE:To catch a target quickly by controlling a main beam electronically according to the target presence probability around target indicating position, and catching the target. CONSTITUTION:In a scanning pattern generating part 1, scanning pattern signals C, D for searching a searching range regulated by a certain target presence probbability are generated. In an addition part 2, the outputs C, D from a target indicating position P and the part 1 are added and the positions are determined successively in higher order of the presence probability of the target. In a phase controlling part 9, respective phase devices 10 are operated in accordance with these searched positions, whereby the direction of the main beam is controlled. As a result, the main beam of phased array antennas 8 search the circumference of the position P until the target is caught. |
