摘要： A radar system includes a radar antenna and a controller. The antenna includes a reference element, an alpha element spaced apart from the reference element by one half-wavelength of the reflected signal, and a beta element spaced apart from the reference element by an even number of half-wavelengths of the reflected signal. The controller is configured to determine an alpha phase difference between detected signals from the reference element and the alpha element, determine a beta phase difference between detected signals from the reference element and the beta element, and determine a first virtual phase difference that corresponds to the reflected signal expected to be detected by a first virtual element located halfway between the reference element and the beta element. The first virtual phase difference is based on the beta phase difference divided by two.

摘要： A dual monopulse/interferometer antenna and radar system. In one example, the antenna includes an active electronically steered monopulse array, and is configurable into an interferometer mode which uses a subset of the array elements of each quadrant of the monopulse array. In one example, the RF feed network that combines signals received from each element in the array to produce monopulse return signals is modified in the interferometer mode to couple out the subset of array elements to produce return signals that are analyzed using interferometric processing.

摘要： A sensor for determining a direction-of-arrival of radiation impingent on the sensor which has antennas positioned in a particular set-up different from a rectangle, so that information may be derived between two pairs of the antennas, positioned in corners of a rectangular grid and additional information may be derived from an additional antenna, combined with one of the “grid” antennas forming a third pair of antennas. The additional antenna is positioned away from the corners and other pre-defined lines of the rectangle/grid. In this manner, such as from phase differences between the pairs of antennas, more information may be derived compared to antennas positioned merely at the corners of a rectangle to remove ambiguous angles of direction-of-arrival without compromising accuracy of an angular determination.

摘要： The invention provides a pulse radar apparatus, and a control method thereof, that permits to readily downsize and to lower its cost and allows information on an object to be detected in high precision by removing an influence of noise when a gain of a variable gain amplifier is discontinuously changed corresponding to detected distance, with a simple configuration. A variable gain amplifier 135 configured to adjust a gain corresponding to a distance gate is used to be able to detect weak reflected wave from a distant object and to amplify a reflected wave from a short distance with a low gain. An offset noise from the variable gain amplifier 135 is prepared together with interference noise and self-mixing noise in advance as a replica signal of unwanted wave and the replica signal is removed from a baseband signal in detecting the object T.
