Latest Patents: Calvin Duc Le's latest patents include:
1. **Interferometric Synthetic Aperture Radar Imaging of Subsurface Structures**: This patent presents a novel subsurface interferometric synthetic aperture radar (InSAR) imaging technique. It is designed for the detection and localization of underground targets amidst a rough ground surface. The two-step process involves surface clutter suppression through a polarimetric difference operation, preserving the propagation phase of the target scattered signal. Following this, a subsurface interferometric algorithm is employed to ascertain target depth by correlating clutter-suppressed images captured along two observation routes.
2. **Change Detection Method and System for Use in Detecting Moving Targets Behind Walls**: This invention outlines a system and method for identifying moving targets concealed behind walls or barriers. The process begins with obtaining multiple images of a specified region, from which a reference image is selected. A series of difference images are generated by subtracting the reference image pixels from those in the remaining images. Negative pixel values are then eliminated, and side lobes are minimized to create a combined difference image. This method can be iteratively applied using different reference images to produce combined difference images that accurately represent the signature of moving targets.
