摘要： An automatic network analyzer that measures continuous wave radio microwave driven transfer characteristics of nonlinear devices and simultaneously calculates and displays corresponding noise driven transfer characteristics and noise power ratio data. This automatic network analyzer employs software or firmware that uses closed-form equations to exactly calculate noise parameters. This is done in real-time as CW measurements are taken.

摘要： Methods and apparatus are provided for determining aperture phase distributions for use in radiating signals with an active phased array antenna having multiple beams and multiple carriers. Distinct initial phase distributions corresponding to the carriers are allocated. The initial phase distributions are modified for each of the carriers to generate respective radiation patterns that substantially correspond to respective coverage areas in accordance with amplification and radiation of signals having the initial phase distributions. The modified phase distributions are optimized to simultaneously increase carrier-signal power and reduce an intermodulation product radiated in the respective coverage areas in accordance with amplification and radiation of signals having the modified phase distributions.

摘要： A dual polarized horn antenna that increases the efficiency of a square or rectangular aperture which may be used in situations where a high efficiency aperture is needed in a constrained space. The antenna has a body that is tapered from a first end to a second end, wherein the first end is smaller in cross section than the second end. A flange is formed around the periphery of the body adjacent to the first end. An opening is formed in the first end of the body. A tuning iris is preferably disposed in the opening that provides for impedance matching. An insert is disposed in the central tapered opening 16 adjacent to the second end that has a central cross-shaped tapered member. The central cross-shaped tapered member extends into the central tapered opening and forms a plurality waveguide passages that form a corresponding plurality of quadrants. A plurality of cross-shaped members are respectively disposed in the quadrants and extend a short distance into the central tapered opening. The antenna may be advantageously used where longer apertures are desired. The antenna has a radiating efficiency on the order of 97 percent.

摘要： A low-profile, electronically scanned antenna that can scan a hemisphere is comprised of three, phased array radiators. Each radiator face has an azimuth and elevation scan angle equal to 120 degrees. The three radiator faces are arranged in a truncated 3 sided pyramid such that they prove continuous hemispherical coverage. The three radiators are mounted to cooled panels of a truncated pyramid-shaped frame such that the radiators enable a full hemisphere to be scanned by radar.
