Coherent radar receiver that comprises a sigma delta modulator

Title: Coherent radar receiver that comprises a sigma delta modulator

Abstract

Described herein are various technologies relating to processing a coherent signal. A receiver is configured to receive an analog signal, and process the analog signal to generate an input analog signal. The input analog signal has been modulated according to a suitable modulation sequence. A coherent signal sampler coherently samples the modulation sequence, and the result of such sampling is in turn used to demodulate the input analog signal. The resultant signal is then passed to a sigma delta modulator, where it is converted to digital form.

Removing interfering clutter associated with radar pulses that an airborne radar receives from a radar transponder

Patent Ormesher, Richard C [Albuquerque, NM]; Axline, Robert M [Albuquerque, NM]

Interfering clutter in radar pulses received by an airborne radar system from a radar transponder can be suppressed by developing a representation of the incoming echo-voltage time-series that permits the clutter associated with predetermined parts of the time-series to be estimated. These estimates can be used to estimate and suppress the clutter associated with other parts of the time-series.

Concentrator-type photovoltaic (CPV) modules, receiver and sub-receivers and methods of forming same

Patent Menard, Etienne; Bower, Christopher; Burroughs, Scott; ...

CPV modules include a back plate having an array of 1 mm2 or smaller solar cells thereon. A backplane interconnect network is also provided on the back plate. This backplane interconnect network operates to electrically connect the array of solar cells together. A front plate, which is spaced-apart from the back plate, is provided. This front plate includes an array of primary lenses thereon that face the array of solar cells. The front plate can be configured to provide a greater than 1000× lens-to-cell light concentration to the array of solar cells. To achieve this 1000× lens-to-cell light concentration, themore »« less

Apodization of spurs in radar receivers using multi-channel processing

Patent Doerry, Armin W.; Bickel, Douglas L.

The various technologies presented herein relate to identification and mitigation of spurious energies or signals (aka “spurs”) in radar imaging. Spurious energy in received radar data can be a consequence of non-ideal component and circuit behavior. Such behavior can result from I/Q imbalance, nonlinear component behavior, additive interference (e.g. cross-talk, etc.), etc. The manifestation of the spurious energy in a radar image (e.g., a range-Doppler map) can be influenced by appropriate pulse-to-pulse phase modulation. Comparing multiple images which have been processed using the same data but of different signal paths and modulations enables identification of undesired spurs, with subsequent croppingmore »« less

Moving receive beam method and apparatus for synthetic aperture radar

Patent Kare, Jordin T [San Ramon, CA]

A method and apparatus for improving the performance of Synthetic Aperture Radar (SAR) systems by reducing the effect of "edge losses" associated with nonuniform receiver antenna gain. By moving the receiver antenna pattern in synchrony with the apparent motion of the transmitted pulse along the ground, the maximum available receiver antenna gain can be used at all times. Also, the receiver antenna gain for range-ambiguous return signals may be reduced, in some cases, by a large factor. The beam motion can be implemented by real-time adjustment of phase shifters in an electronically-steered phased-array antenna or by electronic switching of feedmore » horns in a reflector antenna system.« less
