Title: Innovations of Ivan S Ashcraft
Introduction
Ivan S Ashcraft is a notable inventor based in Marana, AZ (US). He has made significant contributions to the field of detection systems and radar imaging. With a total of 4 patents to his name, Ashcraft's work has advanced the technology used in various applications.
Latest Patents
Among his latest patents is a detection system and method using gradient magnitude second moment spatial variance detection. This innovative system includes a detection processor that receives a frame of image data, performs a rate-of-change of variance calculation, and compares the results with a predetermined threshold to provide output data. The system is designed to work with a range/Doppler matrix that consists of N down-range samples and M cross-range samples.
Another significant patent is the radar imaging system and method using second moment spatial variance. This system also involves receiving a frame of image data and performing a variance calculation with respect to at least one pixel. The calculated variance is then compared with a predetermined threshold to generate output data. The arrangement for performing the variance calculation identifies changes in the standard deviation of localized sampling cells, ultimately producing a variance pixel map.
