A local multipoint distribution service system having an antenna () for transmitting a signal of reused frequency within a specified range from the antenna (), the antenna () having multiple radiating antenna elements, each of the antenna elements being adjusted in phase and in amplitude of radiated signal across the radiationg elements to mitigate radiation above the horizon, and each of the antenna elements being adjusted in phase and in amplitude of radiated signal therefrom to decrease attenuation in radiated power with distance from the antenna ().

Abstract:
Waveguide and/or antenna assemblies for RADAR sensor assemblies/modules, particularly those for vehicles. In some embodiments, the assembly may comprise a waveguide block defining one or more waveguides, each waveguide defined by a waveguide groove. In some embodiments, at least a portion of at least one waveguide groove is non-straight, such as meandering/oscillating back and forth. An antenna structure may be operably coupled with the one or more waveguides, which structure may comprise an array of one or more slots. In some embodiments, a single, elongated slot of the one or more slots may extend along an axis of each waveguide groove for delivering electromagnetic radiation from a corresponding waveguide of the one or more waveguides therethrough.

Abstract:
Antenna structures and assemblies for use in RADAR sensor assemblies and the like. In some embodiments, the assembly may comprise a feed waveguide comprising one or more feeding slots and a parallel plate waveguide operably coupled with the feed waveguide such that each of the one or more feeding slots of the feed waveguide is configured to inject electromagnetic energy into the parallel plate waveguide. A plurality of radiating slots may be formed in a plurality of rows and/or columns extending away from the feed waveguide to deliver electromagnetic energy out of the antenna assembly.

Abstract:
RADAR sensor assemblies/modules, particularly those for vehicles. In some embodiments, the assembly may comprise a plurality of waveguides, each waveguide of the plurality of waveguides being defined by a waveguide groove. A slot may be positioned to extend along an axis of each of the plurality of waveguide grooves. Each of the waveguides may be further defined, at least in part, by a periodic feature that extends back and forth in a periodic manner along at least a portion of its respective waveguide and a plurality of periodic signal confinement structures, a first periodic signal confinement structure of which may extend adjacent to a first side of each of the plurality of waveguides, and a second periodic signal confinement structure which may extend along a second side of each of the plurality of waveguides opposite the first side.

H01Q 21/00 H01Q 5/40 H04B 1/10
Abstract:
Antenna and/or waveguide assemblies for vehicles, such as RADAR sensor antenna assemblies, along with associated signal confinement structures. In some embodiments, the assembly may comprise an antenna block defining one or more waveguides. A conductive layer may be coupled to the antenna block to form, at least in part, a wall of the waveguide. The assembly may comprise one or more periodic structures that may be operably coupled to the waveguide, each of which may comprise a first elongated opening and a first series of repeated slots extending at least substantially transverse to the first elongated opening, wherein each of the first series of repeated slots is spaced apart from an adjacent slot in the first series of repeated slots along the first elongated opening.
System And Method For Calibration And Built-In Self Test Of Automobile Radar System
An I/Q mixer and processing method for a radar system include an RF input and an LO input. Phase shifters apply a selectable phase shift to the LO signal to produce a first phase-shifted version of the LO signal and a second phase-shifted version of the LO signal, the first and second phase-shifted versions of the LO signal being in quadrature. A first set of switches is controllable to selectively apply the selectable phase shift to the LO signal. A first mixer unit receives the RF signal at a first input of the first mixer unit, and a second mixer unit receives the RF signal at a first input of the second mixer unit. A second set of switches is controllable to apply one of the first and second phase-shifted versions of the LO signal to one of a second input of the first mixer unit and a second input of the second mixer unit and to apply the other of the first and second phase-shifted versions of the LO signal to the other of the second input of the first mixer unit and the second input of the second mixer unit. A counter generates a count for sequencing through states of the first and second sets of switches.

There isnt a big group of individuals investigating seafood fraud, said Scott Doyle, a recently retired NOAA investigator who now advises conservation groups and foreign governments on how to fight crime. They cut the investigators in half, he said. Thats a poor response.

Whale that had been shot washes ashore, dies in New Jersey
Scott Doyle of the National Oceanic and Atmospheric Administration, which was notified of the whale's existence after it was found on the beach, told the newspaper that it's not unusual to have "two or three" shootings of dolphins and seals each year, but in 25 years on the job he had never encounte
Scott Doyle with the National Oceanic and Atmospheric Administration told The Star-Ledger of Newark ( http://bit.ly/qFYJDF) this is the first time he can remember a whale being shot in his 25 years on the job.
