Latest Patents

One of Hjelmstad's latest patents is titled "Method and system for automatic classification of objects." This invention aims to enhance the speed and robustness of existing Inverse Synthetic Aperture Radar (ISAR) classification methods. The method generates a set of silhouettes of potential models from a 3D model database. These silhouettes represent the model from various viewing angles, accommodating the changes in target dimensions as viewed from different perspectives. The silhouettes are compiled into a training set, and classification is achieved by comparing the target's silhouette with those in the training set. The silhouettes are calculated prior to the matching process.

Another significant patent is the "Method and arrangement for determining the spatial frequency of a signal." This invention provides a technique for identifying the direction of an emitter source by analyzing the spatial frequency of a signal received from the source through a sensor panel. The panel consists of a first matrix of sensors and a second matrix interleaved with the first. The spatial frequency is determined by comparing the signals from both sensor matrices.
