<p>PROBLEM TO BE SOLVED: To constitute a phase correcting device of an active phased array radar for satellite mounting which has large restriction of weight by restraining the increase in the weight. SOLUTION: A phase correcting device in an active phased array radar device mounted in a satellite forms a directional coupler 7 with strip line at an output end for every one transmitting and receiving module 2 on an antenna 3 to which a plurality of transmitting and receiving modules 2 are connected and an output signal from the directional coupler is formed with one strip line. Whereby, the increase in weight caused by the addition of the directional coupler 7 is restrained and a phase comparator is removed to lighten the device by using frequency converting function which is the function of a receiver itself for measuring phase difference.</p> |
