SEARCH AND RESCUE RADAR TRANSPONDER

摘要

The present invention provides a search and rescue radar transponder easy in maintenance and checking. In the search and rescue radar transponder of the invention, the transmission electric power of the transmitting circuit 3 leaked at the changeover switch 7 is inputted to the receiving circuit 2, and whether the search and rescue radar transponder operates normally or not is judged by comparing the leaked electric power level detected by the receiving circuit 2 with a prescribed level at the controlling circuit 4. Hereby, the operation-checking of the search and rescue radar transponder proper other than an antenna can be execute by a built-in apparatus, and its maintenance and checking can be executed easily and rapidly.
