Abrégé

Disclosed is an arrival direction estimation device comprising a control unit for estimating the arrival directions of wireless signals by reception direction scanning and receiving the wireless signals. The control unit estimates the arrival directions of received wireless signals using a first arrival direction estimation method, excludes a wireless signal having an arrival direction with a reception power value from among estimated wireless signal reception power values that is less than or equal to a prescribed threshold or excludes a wireless signal having an arrival direction outside of the range of a main beam having the maximum peak value from among the estimated wireless signal reception power values, and estimates the arrival directions of the received wireless signals using a second arrival direction estimation method having a greater resolution than the resolution of the first arrival direction estimation method.
