Title:
目標距離推定装置、電波探知装置、及び目標距離推定方法
Document Type and Number:
Japanese Patent JP7286033
Kind Code:
B2
Abstract:
A target distance estimation device (3) includes: a multipath composite wave signal generation unit (11) 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 (20) in a case where a provisional target distance, which is a provisional target distance from a radio source to a radio wave detection device (100), is set; and a target distance estimation unit (12) that estimates a target distance from the radio wave detection device (100) 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 (11).
