    摘要: In one embodiment, an improved transceiver assembly for a vehicle capable of detecting potentially hazardous objects is disclosed. The transceiver assembly comprises a tapered slot feed antenna for generating a beam and for detecting the beam as reflected from the potential hazards. The antenna is formed in or on a housing which also contains a parabolic dish that oscillates to sweep the beam of radiation towards the potential hazards outside of the vehicle. In a preferred embodiment, approximately 77 GHz radiation is generated from and detected by the antenna. The antenna is preferably formed on a printed circuit board (PCB) (substrate), which can include additional circuitry necessary to operate the antenna, and which is preferably mounted at an acute angle with respect to the housing to direct the beam at the parabolic dish.

    摘要: An antenna system (205) includes an antenna structure (215), a receiver (220), and an antenna system controller (225). The antenna structure includes an arrangement of antennas (237), a signal combiner (240), and a switching matrix (235). The arrangement of antennas is designed to have a set of antenna element separations that are optimized to provide lowest correlation coefficients of intercepted radio signals for a corresponding set of electromagnetic environment types that vary from a very low density scattering environment to a maximum density scattering environment. The antennas (230), (231), (232), (233), (234) in the antenna arrangement each include at least one element that has a common polarization. There is at least one antenna that is a dual polarized antenna. The antenna system selects an antenna element pair that corresponds to the environment type which it is operating and thereby receives a best combined signal.
