PURPOSE:To attain to enhance preciseness in automatically tracking radio wave direction, by providing a means wherein the polarization of a rader wave is automatically distinguished to be converted to the corresponding polarization after an antenna is directed and induced based on radar wave receiving information and the direction of a radio wave is automatically tracked while the turblence of a radio wave axis/a machine axis is minimized. CONSTITUTION:The outputs of a horizontal in-plane non-directional antenna 1 and a single directional antenna 3 for detecting an arrival direction are rspectively inputted in a receiver 2 for detecting the repeating of a pulse and a direction detecting receiver 4. The outputs of receivers 2, 4 decide the use state of an objectie radio wave and are inputted in a signal treating device 5 for sending an indication signal to a display controller 6 and a response transmitter receiver 10. The data from the treating device 5 is inputted in the display controller 6 showing various origins of the radio wave and the horizontal direction controlling servo amplifier 7 of the transmitting and receiving antenna 9 drives a servo mechanism 8 based on initial directional information to direct and control the antenna 9 in a predetermined direction. A following receiver 11 changes over the transmission polarization of a transmitting antenna based on the initial directional information to the corresponding polarization to automtically track the direction of a radio wave. |
