Abstract
In a distance estimating system, a first terminal transmits a response request signal and successively transmits impulse signals as synchronization signals, and a second terminal receives the response request signal, generates response data based on the response request signal, shifts a bit, which is a transmission target in a bit string as the response data, by one toward a rear side from a leading bit to a trailing bit each time the synchronization signal is received, transmits the impulse signal in a case where a value of a bit that is a transmission target at a time of reception of the synchronization signal is a predetermined value. The first terminal further measures a round-trip time, specifies a flight time of the impulse signal, and estimates a distance to the second terminal based on the flight time and a propagation velocity of the impulse signal.
