A transmission / reception means mounted on a moving body such as an aircraft and having transmission means for radiating a radar transmission wave into space and a receiver for receiving a reflected wave from a target, and a reception signal received by the transmission / reception means. A radar device equipped with a signal processor that performs radar signal processing on target equipment. A target jammer from an electronic warfare support device that is mounted on the same moving body as the radar device and detects the specifications of jammers radiated from the target. Using the center frequency, bandwidth, and time rate of change of the frequency, calculate the amount of change in frequency so that the target interference wave does not enter the reception bandwidth of the receiver of the radar device during transmission by the radar device, and calculate the transmission frequency. Characterized in that a transmission frequency changing means for changing the frequency is provided.
