摘要： A phased-array receiver (600) comprises a plurality of analog beamforming receive channels (602), each comprising an antenna element (610) arranged to receive a radio frequency signal and a channel output (628) arranged to provide an analog channel output signal. At least one of the plurality of analog beamforming receive channels comprises an in-phase downconversion mixing circuit (614) connected to the antenna element and a local oscillator source (616) and arranged to provide a downconverted in-phase signal to a phase rotation circuit (612), and a quadrature downconversion mixing circuit (620) connected to the antenna element and the local oscillator source and arranged to provide a downconverted quadrature signal to the phase rotation circuit. The phase rotation circuit is arranged to provide to the channel output a phase-shifted analog output signal generated from the downconverted in-phase signal and the downconverted quadrature signal.

摘要： An electronic scanning radio direction finding system (1) for accurate direction finding of radio frequency signals using singly or doubly flared cylindrical reflectors (2) surrounded by a circular array of inwardly facing feed horns (9). The array is operated as a phased array to determine the direction of origin of received signals. The feed horns (9) can also be used to transmit RF signals on very narrowly controlled beams with minimal side lobes. The flared cylindrical reflector (2) and its circular feed horn array may be paired with circular log periodic arrays operable at similar frequency ranges or different frequency ranges to provide more precise direction finding and direction finding of signals at frequencies beyond the range of the flared cylindrical reflector (2) and its circular feed horn array (9).

摘要： A controller is configured to operate an antenna positioner, which positions an antenna to track a moving object during a pass, in dual operational modes. The controller determines a maximum expected elevation angle during the pass. The controller de-activates the azimuth drive assembly and activates the x-axis drive assembly and the y-axis drive assembly, if the maximum expected elevation angle is greater than or equal to a predetermined angle. The controller de-activates the x-axis drive assembly, and activates the azimuth drive assembly and the y-axis drive assembly, if the maximum expected elevation angle is less than the predetermined angle.

摘要： An antenna for use in a direction finder system, said antenna including a microstrip patch layer with a stripline transmissionline layer below. The microstrip layer and the stripline layer share a common groundplane. In this groundplane is formed a number of apertures. Each aperture couples a patch to a radiation point in the stripline feed layer. The patches and transmissionlines are designed from a lossy material. The substrates in the microstrip and stripline layers may be designed from materials with lossy dielectric properties.

摘要： The present invention relates to methods and systems for time-multiplexing a single VOR receiver to determine bearings from two or more VOR stations and thus determine a relative position of an object such as an aircraft. The invention employs a software-programmable digital signal processor (DSP) to process the VOR signals and control the amplifier stage. The gain control parameters that are used to process the VOR signals are stored for each processed carrier frequency so that the VOR signals may be quickly and releably acquired; thus, enabling the time-multiplexing of the VOR receiver.
