Abstract
A target distance estimation device includes: a multipath composite wave signal generation unit that generates a multipath composite wave signal that is a simulation signal of a composite wave of a direct wave and a multipath wave received by a reception antenna in a case where a provisional target distance, which is a provisional target distance from a radio source to a radio wave detection device, is set; and a target distance estimation unit that estimates a target distance from the radio wave detection device to the radio source on the basis of a correlation between the reception signals and the multipath composite wave signal generated by the multipath composite wave signal generation unit.
