ヒーレントトランスポンダ用送信装置。means for determining synchronization of a receiving device constituting the transponder with a received signal based on a change in state of a squelch on-off signal of the receiving device; and a control signal for switching to coherent mode when the determining means detects synchronization with the received signal. means for generating a control signal for setting the non-coherent mode when synchronization is not detected, and a voltage synchronized with the received signal of the receiving device when the control signal for setting the coherent mode is input. a first switching means that switches to the output of the controlled oscillator and switches to the internal oscillator output of the transmitting device when a control signal for switching to the non-coherent mode is input, and a command signal from the fixed station to switch between the coherent mode and the non-coherent mode. a second switching means for permitting or prohibiting mode switching; and a second switching means for transmitting a transmission data signal or a ranging signal using the output of the voltage controlled oscillator or the internal oscillator output selected by the first switching means as a carrier wave. A transmitting device for a coherent transponder comprising a conveying means.
