Incoming wave classification distinction device, incoming wave classification distinction method, dispatch position presumption device and dispatch position presumption method

摘要

Even under multiple pass environment, the device and the method where it can distinguish the position of classification and the transmitter of the incoming wave just. The vertically polarized wave principle wave arrival direction sensing station (the 104 1) and the horizontally polarized wave principle wave arrival direction sensing station (the 104 2), by the fact that the arrival direction where respectively, you can obtain maximum reception level is detected, arrival direction of the principle wave is detected. The incoming wave classification decision section (108), when difference of arrival direction of the principle wave which is detected arrival direction and the horizontally polarized wave principle wave arrival direction sensing station of the principle wave which is detected the vertically polarized wave principle wave arrival direction sensing station (the 104 1) by (the 104 2) by is within specified threshold, it decides, that the direct ray has arrived, when the aforementioned difference it is larger than the aforementioned threshold, it decides that the direct ray has not arrived.
