摘要： Lower-limit frequency reflection characteristics of a horn antenna (2) are improved even though element spacing, of less than or equal to one wavelength, is a spacing at which grating lobes do not occur in an antenna radiation pattern. The horn antenna (2) includes a horn antenna (2) and a conductor grid (1) that divides an aperture A (4) of the horn antenna (2) in a grid pattern and that electrically connects to an inner surface of the horn antenna (2) at the aperture A (4) of the horn antenna. Width of the conductor grid (1) in a direction orthogonal to a horn antenna aperture plane differs from electrical length of the path of the horn antenna (2) of the conductor grid (1) portion at the frequency of power supplied to the horn antenna (2).

摘要： The design and use of a simplified, highly efficient, waveguide-based wireless distribution system integrated with a carrier tray are provided. A low-loss waveguide (131,133) is used to transport wireless signals from a signal source or sources to one or more receiver locations. One or more adjustable signal coupling devices (52) partially insert into the waveguide at predetermined locations along the length of the system to provide variable, controlled extraction of one or more wireless signals. Low-loss impedance matching circuitry is provided between the waveguide coupling devices and output connectors to maintain high system efficiency. The system offers the capability of supplying signals of high strength and high quality to a large number of receivers in a wide wireless coverage area via a plurality of signal radiators. Some embodiments of the system are readily adaptable for wireless distribution service in HVAC plenum spaces. A system that combines the functions of fire extinguishing and waveguide wireless distribution is also disclosed.

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.
