Abstract
Official abstract text for this publication.
A device for detecting an azimuth has a transmission array antenna having plural transmission antenna elements arrayed along an array axis and a receiving array antenna having plural receiving antenna elements arrayed along the array axis. A reception signal is acquired for each of channels by transmitting and receiving a search wave through each of the channels. The channels are arbitrary combinations of each of the transmission antenna elements and each of the receiving antenna elements. A first spatial frequency analysis is performed along the array axis of either ones of the transmission antenna elements and the receiving antenna elements using the reception signal. A second spatial frequency analysis is then performed along the array axis of the other ones of the antenna elements using results of the first spatial frequency analysis. An azimuth of a target is determined based on analysis results from the second spatial frequency analysis.
First claim
Opening claim text (preview).
What is claimed is: 1. A device for detecting an azimuth viewed from the device which is present in a field, the device comprising: a transmission array antenna having M-piece transmission antenna elements (M is an integer equal to or larger than 2) arrayed along an array axis set in advance and a receiving array antenna having N-piece receiving antenna elements (N is an integer equal to or larger than 2) arrayed along the array axis, wherein N×M-piece channels for transmission an…
