摘要： A system and a method for switching antenna fields without waiting until data packets containing errors are detected. This is accomplished by monitoring the signal power for each antenna field immediately after receipt of data packets via the currently active antenna field and then switching to another antenna field having greater signal power. A communications channel is provided which has a capacity greater than that required by the data to be transmitted. This extra capacity is used to introduce time periods when no data is being transmitted. During these time periods, known bit patterns are transmitted, and the signal power during receipt of each of these blank packets is estimated for each antenna field. The receiver then switches to the most appropriate antenna field based on highest signal power (e.g., based on a weighted average for the N-th most recent sample periods) and continues to receive the transmitted data without interruption.

摘要： Methods, systems and computer program products for nondestructive ultrasound imaging are provided. An example method defines a plurality of subarrays, each comprising a plurality of ultrasound transducer elements. The method transmits a plurality of ultrasound beams from each of the plurality of subarrays, each ultrasound beam being transmitted at a preset beamsteering angle. Subsequent to each transmit, the method receives, at the array, a plurality of ultrasound reflections corresponding to the plurality of ultrasound beams. For each point to be imaged, the method selects one set of received element data for each of the plurality of subarrays. The selected set of element data corresponds to an ultrasound beam having a focal point closest to the point to be imaged. Finally, the method reconstructs a point to be imaged based on the selected received element data, and constructs an ultrasound image by repeating this process for each point to be imaged.

The system includes an imaging detector configured to detect radiation originating from at least one source of radiation over a pre-determined period of time or distance traveled. The system also includes a processor coupled to the imaging detector. The processor is configured to backproject the radiation detected onto multiple points in world space via an image reconstruction technique. The processor is also configured to generate a first set of image pixels identifying a location of the source of radiation corresponding to each of the points in world space, wherein the first set of image pixels indicate presence of all possible sources of radiation. The processor is further configured to generate a second set of image pixels from the radiation backprojected, identifying only one or more potential sources of threat via a threat detection algorithm.
