    摘要: In an antenna apparatus, a transmitting antenna includes transmitting-side unit antennas arranged in an arranging-direction at transmitting-side arrangement intervals. Receiving antennas are arranged in the arranging-direction at arrangement intervals. Each of the receiving antennas includes receiving-side unit antennas arranged in the arranging-direction at receiving-side arrangement intervals. The receiving-side arrangement interval is larger than the transmitting-side arrangement interval. A transmission- and reception composition characteristic, which is a composition of directivities of the transmitting antenna and receiving antenna, has a main lobe including a detection angle range. The transmitting-side arrangement interval and the receiving-side arrangement interval are determined so that, in the detection angle range, a ratio of the intensity of the main lobe of the transmission-and-reception composition characteristic at a given angle in the detection angle range to the intensity of the transmission-and-reception composition characteristic generated as a false image at the angle by wrap around becomes not less than a threshold.

    摘要: 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.

    摘要: A plurality of array antenna elements are divided in terms of a set constituted of an optionally selected L number of groups. The spaces between the array antenna elements are determined by obtaining a greatest common divisor of the set as a greatest common divisor of inter-group element spaces, the set having, as components, greatest common divisors of inter-element spaces of the individual L number of groups in the set, obtaining a greatest common divisor of inter-group element for every number L equal to or less than the maximum number of incoming waves by changing the number L of group components, and allowing a direction not to be caused in the radar scanning region by a number equal to or more than L+1, on the basis of the greatest common divisor of inter-group element spaces for every number L of group components, the direction being linearly dependent on an incoming wave corresponding to the greatest common divisor of inter-group element spaces.
