Ground imaging system for analyzing electromagnetic radiation signatures
The granted patent US12046032B2 describes a sophisticated ground imaging system designed for integration with a guided aerobody. This system features multiple lenses that capture electromagnetic radiation from ground-level objects and terrain. A filter substrate, positioned at the focal plane of the lenses, incorporates various filters, including polarization and multispectral filters, organized in columns. The system includes a sensor array that receives the filtered electromagnetic radiation, and a processing device that analyzes the multispectral and polarization signatures to identify whether certain objects are undesired targets. The filter substrate is divided into two regions, each corresponding to different distances from the aerobody, allowing for enhanced imaging capabilities.
Additionally, the processing device may utilize a field programmable gate array (FPGA) for efficient data processing. The sensor array is organized into groups, with the first group being larger than the second, and it is designed to handle varying pixel sizes based on the distance of the objects being imaged. The system also allows for the analysis of unfiltered electromagnetic radiation, providing further contrast signatures. The polarization filters are specified as thin film linear polarizers, while the multispectral filters include notch filters. An actuator is included to enable movement of the filter substrate relative to the sensor array, enhancing the system's adaptability. Overall, this patent outlines a comprehensive imaging solution that leverages advanced filtering and processing techniques to improve ground-level object detection and analysis.
