Application: Radar using end-to-end relay (Patent ID: US20230417903A1)

The patent filed by ViaSat Inc. describes a multi-static synthetic aperture radar system that uses beamforming processing to generate radar images. The system processes feed element signals from satellites or access node terminals according to multiple beam weight sets, each corresponding to a specific beam coverage pattern. These processed signals are then combined to obtain image pixel values, which are further combined to generate an image. The method involves processing multiple sets of feed element signals over different time periods to form the final image.

The patent also includes claims detailing the method for imaging using a satellite, which involves receiving return downlink signals at a satellite access node, processing these signals according to various beam weight sets to obtain beam signals, and ultimately generating an image of the illuminated geographical region. The claims further elaborate on the processing of signal data, beam coverage patterns, and the combination of image data points to create a comprehensive image. Additionally, the patent covers various scenarios such as the transmission of beacon signals, relayed reflections, and interactions between multiple satellites. Overall, the patent outlines a sophisticated imaging system that leverages beamforming processing to enhance radar imaging capabilities.
