PURPOSE:To operate efficiently the transmitting power of a transmitter used for search and tracking, by performing the feedback control of the distribution ratio of the transmitting power in accordance with an excess tracking radar receiving power detection value. CONSTITUTION:A tracking radar receiving power is detected through a tracking antenna 4, a tracking receiver 5, etc.; and if the receiving power detection value is excess because a target is at a short distance or is large-scaled, the feedback control of a variable power distributor 12 is performed by a power distributor driving circuit 13. Thus, the distribution ratio to power for tracking and power for search of the transmission output of a transmitter 1 used for tracking and search is adjusted automatically, and the transmission output is operated efficiently without damaging the tracking precision. |
