摘要： An antenna element is described which has at least one radiator layer disposed over a feed circuit layer. The radiator has a first ground plane disposed thereon and the feed circuit layer has a second ground plane disposed thereon. A conductive path couples the first and second ground plane layers to provide a cavity in the radiator and feed circuit layers. The cavity may be formed by embedded vias which provide a continuous conductive path between the first and second ground plane layers. A cover layer disposed over the radiator layer may function to tune the antenna element. The radiator layers may be provided from a low temperature co-fired ceramic substrate. Apertures in the radiator layers may be used to match an impedance of the antenna element to a predetermined impedance.

摘要： A short range millimeter wave imaging radar system. The system includes electronics adapted to produce millimeter wave radiation scanned over a frequency range of a few gigahertz. The scanned millimeter wave radiation is broadcast through a frequency scanned transmit antenna to produce a narrow transmit beam in a first scanned direction (such as the vertical direction) corresponding to the scanned millimeter wave frequencies. The transmit antenna is scanned to transmit beam in a second direction perpendicular to the first scanned direction (such as the horizontal or the azimuthal direction) so as to define a two-dimensional field of view. Reflected millimeter wave radiation is collected in a receive frequency scanned antenna co- located (or approximately co-located) with the transmit antenna and adapted to produce a narrow receive beam approximately co-directed in the same directions as the transmitted beam in approximately the same field of view. Computer processor equipment compares the intensity of the receive millimeter radar signals for a predetermined set of ranges and known directions of the transmit and receive beams as a function of time to produce a radar image of at least a desired portion of the field of view. In preferred embodiment the invention is mounted on a truck and adapted as a FOD finder system to detect and locate FOD on airport surfaces.

摘要： A radar detection process includes computing a derivative of an FFT output signal to detect an object within a specified detection zone. In one embodiment, a zero crossing in the second derivative of the FFT output signal indicates the presence of an object. The range of the object is determined as a function of the frequency at which the zero crossing occurs. Also described is a detection table containing indicators of the presence or absence of an object within a respective radar beam and processing cycle. At least two such indicators are combined in order to detect the presence of an object within the detection zone and with changing range gates in each of the antenna beams the coverage of the detection zone can be varied.

摘要： An improved antenna array (100) comprises a set of array elements (102 a-p) electromagnetically coupled to a transmission line. The transmission line comprises a live conductor (122) and a return conductor, and the live conductor (122) is terminated by a direct connection to the return conductor. An input signal fed to the live conductor (122) is radiated by the array elements (102 a-p) and the antenna array (100) is arranged such that any portion of the input signal reaching the termination is reflected at the termination so as to form a reflected signal that superimposes with the input signal to produce a predetermined farfield radiation pattern.
