Abstract
PURPOSE:To ensure a high-accuracy orientation for the position of the electric wave source by utilizing the time difference between the direct wave form the electric wave source and the reflected wave from plural units of electric wave reflectors. CONSTITUTION:The radiation source position orientating device comprises antenna 1 to receive the direct wave from electric wave source 8 and the reflected waves from electric wave reflectors 6a-6n such as buoys arranged as if they were floating in the air, receiver 2, time difference detector circuit 3 to detect the time difference between the direct wave and the reflected wave, and process circuit 4 to orientate the position of the output and the reflectors plus the position of the wave source based on the position of the self-side machine respectively. Thus, the orientating device is installed to moving object 5 like airplanes or the like in order to orientate the target position. In other words, circuit 3 detects time differences T1-Tn between direct wave 9 and reflected waves 10a-10n. The position orientation is performed by calculating the fulcrum of plural hyperbolic curves with the positions of the reflectors and the self-side machine position as the focal points. And this orientating method can be used for the position orientation for the radiation sources of the sound wave and the ultrasonic wave.
