  • Radar device for detecting response signal
    Patent number: 6507310
    Abstract: When a question signal of a transmitting frequency band &Dgr;F1 output from a radar device is received in search and rescue radar transponder (SART) of a wreck ship, a response signal is sent from the SART to the radar device. In the radar device, the response signal and an echo of the question signal are received as a reception signal, intensity of components of the reception signal placed in almost the same frequency band as the transmitting frequency band &Dgr;F1 of the question signal is suppressed to produce a filtered response signal, and components of he filtered response signal placed in a receiving frequency band &Dgr;F2, which does not overlap with the transmitting frequency band &Dgr;F1 of the question signal, are extracted from the filtered response signal as an image signal.
