PURPOSE:To make the device small-size and light in weight, expand its available range and exactly perform tracking, by using a micro strip line for the hybrid circuit which is used for the input circuit of a tracking receiver, and also using a cathode ray tube as the display means. CONSTITUTION:In the input circuit, 4 hybrid circuits 18-21 calculated the sum total of outputs of each horn antenna 8-11, the output DELTAAZ(M) which is proportional to the magnetic declination error DELTAAZ, and the output DELTAEL(M) which is proportional to the elevation angle DELTAEL. A micro strip line which has been made from a rat race circuit by use of the technology of the printed circuit board is used for a hybrid circuit. And this device is provided with 4 terminals which are of a ring form having the circumferential length of 6/4lambda and are mutually adjacent to intervals of lambda/4, and when signals X, Y are input from two terminals among them respectively, the respective sums and differences are output from other two terminals. |
