摘要： A radar apparatus forming a series-feed array-antenna includes an array antenna having transmission/reception antennas, and each antenna includes a plurality of antenna elements arrayed with feed-lines to be series-connected each other. A calibration line is disposed between the transmission antenna and the reception antenna via a switch which connects or disconnects the calibration line. The signal having a phase shift is transmitted via the calibration line when the switch connects the calibration line and an amount of phase shift from the signal transmitted via the calibration line is calculated based on a reference phase at the transmission antenna thereby calibrating the phase shift.

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.
