Radio wave generation source visualization device and radio wave generation source visualization manner

摘要

P To provide a device and a method for visualizing a radio wave generation source that can search for a signal in a frequency range of a broad-band, in a short time and for specifying a radio wave generation source effectively and then can visualize the source. PSOLUTION: The device includes an A/D converter that obtains digital data, corresponding to signals received by a reference antenna and a plurality of other antennas, after receiving radio waves inputted to the reference antenna and a plurality of the antennas to frequency-convert the waves, and an arithmetic processor that is operable in two modes, which has one of the modes frequency-analyzes the received signals, based ON the digital data of a signal received by at least one of antennas and another mode that receive signals in a specified frequency band for estimating the arrival direction of the radio waves to output two-dimensional images and using the correlation values of digital data of the signals received by the reference antenna and a plurality of the antennas. Then, the mode is selected and controlled and in response to the operation of the operator. PCOPYRIGHT: (C)2007 and JPO& INPIT
