1. A transmission and reception apparatus comprising:
- a transmitter circuit including a first signal generator to output, to an object, a first plurality of pulses being arranged at intervals of a step frequency and a first switch; and
a receiver circuit including a second signal generator and a second switch,wherein the first switch couples an output of the first signal generator to a transmitter terminal in a first mode and couples the output of the first signal generator to the second signal generator in a second mode,the second switch couples a receiver terminal of a reflection signal reflected by the object to the second signal generator in the first mode and couples the reception terminal to a terminator in the second mode.
