<p>A finder for finding the bearing/location of a radio wave emission source with high accuracy. The finder comprises first and second directional antennas rotating with a desired angle of elevation, first and second phase integration means for outputting the integration of the antenna outputs, first and second phase difference means for outputting the difference between the antenna outputs, first and second frequency division means for dividing the frequency of the integration component of the antenna outputs, first and second difference gain regulation means for regulating the gain of the difference component of the antenna outputs, first and third receiving means for receiving the outputs from the frequency division means, second and fourth receiving means for receiving outputs from the difference gain regulation means, first and second subtraction means for subtracting the detection signal outputs sent from the receiving means, first and second calculation means for determining the azimuth of the incoming radio wave from the outputs of the subtraction means, and location determining/calculating means for determining the location from the outputs of the calculation means.</p> |
