His work focuses on enhancing the capabilities of radar systems, particularly in satellite applications.

Latest Patents

One of Schaefer's latest patents is titled "Synthetic aperture radar data reduction for satellites." This invention presents a preprocessing technique for synthetic radar images. The method involves receiving range-compressed radar data generated from raw radar image data on-board a satellite or an airborne vehicle. It includes generating a preliminary SAR image through pre-focusing on the range-compressed radar data, extracting image subsectors from the preliminary SAR image, and transmitting these subsectors to an on-ground portion. The process further reconstructs the range-compressed radar data related to the extracted subsectors, making it available for a nominal synthetic aperture radar processor. This processor is designed to generate a focused SAR image with a higher resolution than that of the preliminary SAR image.

Another notable patent is for a "Radar system with synthetic aperture." This SAR system includes a radar antenna with at least one partial antenna, each containing multiple phase centers equipped with transmit/receive modules. The system features a signal processor for coherent processing of signals from the phase centers. The signal processors incorporate a hybrid beam forming module that digitizes and processes analog receive signals, converting them into analog signals. An analog receive network combines these signals to form an output signal.
