Title:
RADIO WAVE EMISSION SOURCE VISUALIZING DEVICE, AND BANDWIDTH EXPANSION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/182347
Kind Code:
A1
Abstract:
According to an embodiment of the present invention, a radio wave emission source visualizing device is provided with an antenna unit, a selecting unit, an estimating unit, an image capturing unit, and a creating unit. The antenna unit is provided with N (where N is a natural number at least equal to 2) antenna elements arranged in an array, and captures an incoming wave. In accordance with the bandwidth of the incoming wave, the selecting unit selects an antenna element group including M (where M is a natural number at most equal to N) antenna elements from among the N antenna elements. The estimating unit estimates the arrival direction of the incoming wave from element signals of each antenna element included in the selected antenna element group. The image capturing unit obtains image data by capturing an image in the orientation direction of the antenna unit opening. The creating unit creates a visualized image by visually synthesizing the estimated arrival direction onto the image data.
