Abstract

PURPOSE:To prevent radio interference and to prohibit the generation of a response wave to a side lobe, by sending out a response wave from a child station radar buoy only when the microwave from the radar apparatus of a key station is received. CONSTITUTION:A radar antenna 1 transmits and receives a searching pulse (microwave) while revolving at a constant cycle. A radar buoy key station 4 drives a VHF wave oscillator 46 after the transmission of the microwave and a VHF wave is sent out from an antenna 42. A radar buoy child station 6 drives a child station code generator 67 only when the signal obtained by delaying the microwave received by an antenna 62 by a delay circuit 64 and the VHF wave signal received by an antenna 61 are simultaneously inputted to an AND circuit 66 to send out a response signal from the antenna 61. Since the child station 6 responds only when the delay times of delay circuits 46, 65 are equal, radio interference can be prevented. Further, since the child station 6 adjusts the amplification degree of a microwave receiving signal corresponding to the receiving intensity of the VHF wave, the response to a side lobe can be prevented.
