PURPOSE: To realize the transmitter-receiver in which an observation fault of a desired reception wave signal due to a reception interference wave causing interference from a sender side to a receiver side is excluded with comparatively simple configuration when transmission of a pulse signal and reception of a pulse signal are simultaneously implemented in the transmitter-receiver provided with an interference wave suppression means.
CONSTITUTION: A transmitter 1 of a sender side is provided with a pulse transmission signal generating means 11A and a broad band signal generating means 12 generating a broad band signal to add a broad band signal to a transmission signal. An interference wave suppression means 10 at a receiver side is provided with an adaptive filter 7 receiving part of the transmission signal with the broad band signal at the sender side added thereto and simulating a reception interference wave signal causing interference from the sender side to the receiver side, and with a subtractor means 8 subtracting an output signal of the adaptive filter from an output signal of a receiver 2. An observation fault of a desired reception wave signal s(k) due to the reception interference wave causing interference from the sender side to the receiver side is excluded without complicated configuration by expanding the frequency band of the reception interference wave suppressed by the adaptive filter.
