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 power-supply device for supplying electrical power to a radar device that transmits and receives a continuous wave and detects an object reflecting the continuous wave on the basis of a spectrum of a beat signal of the transmitted and reflected waves. The power-supply device includes a power supply section that generates electrical power in a predefined voltage range through a switching section being turned on and off in response to a switching signal, and a switching signal output section that, outputs the switching signal whose frequency is set within one of assignable bands. This leads to a radar system comprised of the radar device and the power-supply device, capable of securely preventing erroneous detection of a frequency peak of the switching signal as a frequency peak of the object.

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.

摘要： A radar apparatus has a plurality of receiving antennas and an array transmitting antenna controlled to successively vary the direction of a transmitted beam within a range which includes a target detection range of directions. The direction of any target within the target detection range is detected based on a phase difference between incident reflected waves of adjacent receiving antennas. To eliminate false targets resulting from aliasing, each detected target is authenticated based upon closeness of its detected direction to the current transmitted beam direction. The receiving antennas and transmitting antenna are configured to exclude directions of grating lobes of the transmitted beam from the detection range, and thereby suppress effects of received reflected waves that originate from grating lobes.

摘要： In a FM-CW or CW radar apparatus, when interference components are contained in channel signals obtained as beat signals from array antenna elements of respective channels, and the interference components result from directly receiving transmitted CW radar waves from an external source, phase shifting is applied to each of the channel signals to shift respective phases of the interference components of the respective channels to a condition corresponding to reception of interference waves from a predetermined direction. The interference components are then eliminated, and reverse phase shifting is applied to restore remaining components of the channel signals to their original phase condition.

摘要： Occurrence of interference is detected using sampled amplitude data obtained by oversampling a beat signal. It is detected by comparing the absolute value (|VD|) of variation in the sampled data with a threshold value (TH). When interference occurs, a wideband signal is superposed on the beat signal, and this disturbs the signal waveform of the beat signal to drastically varies its amplitude. Therefore, occurrence of interference can be detected without fail regardless of the scheme on which a radar as the source of an interference wave is based and even when the amplitude of the interference wave is low. In addition, when low-frequency noise is superposed on the beat signal, erroneous detection of occurrence of interference can be prevented.
摘要翻译：使用通过过采样拍频信号获得的采样振幅数据来检测干扰的发生。通过将采样数据的变化的绝对值（| VD |）与阈值（TH）进行比较来检测。当发生干扰时，宽带信号叠加在节拍信号上，这样会扰乱拍频信号的信号波形，从而大大改变其幅度。因此，即使干扰波的幅度低，雷达作为干扰波的来源，即使是干扰波源也是可以的，所以能够毫无疑问地检测出干扰的发生。此外，当低频噪声叠加在节拍信号上时，可以防止发生干扰的错误检测。
