電波発射源可視化装置および帯域拡大方法
Document Type and Number:
Japanese Patent JP7362521
Kind Code:
B2
Abstract:
According to one embodiment, an apparatus includes antenna(2), selector(3), estimator(7), imager(8) and creatior(9). The antenna(2) includes N (N is a natural number of 2 or more) antenna elements(1-1 to 1-n) arranged in an array and captures an incoming wave. The selector(3) selects an antenna element group including M (M is a natural number of N or less) antenna elements from the N antenna elements(1-1 to 1-n) according to a band of the incoming wave. The estimator(7) estimates an incoming direction of the incoming wave from an element signal of each of the antenna elements(1-1 to 1-n) included in the selected antenna element group. The imager(8) acquires image data by imaging an orientation direction of an aperture of the antenna(2). The creator(9) creates a visualized image by visually synthesizing the estimated incoming direction with the image data.
