  • Radio wave emission source visualization apparatus and band expansion method
    Patent number: 12262220
    Abstract: An apparatus includes antenna, selector, estimator, imager and creator. The antenna includes antenna elements of N rows by N columns (N is a natural number of 2 or more) arranged in an array and captures an incoming wave. The selector selects an antenna element group including antenna elements of M rows by M columns (M is a natural number less than N) from the antenna elements of N rows by N columns according to a band of the incoming wave. The estimator estimates an incoming direction of the incoming wave from an element signal of each of the antenna elements included in the selected antenna element group. The imager acquires image data by imaging an orientation direction of an aperture of the antenna. The creator creates a visualized image by visually synthesizing the estimated incoming direction with the image data.
