Title: The Innovations of David Nikolaus Perkins: A Pioneer in Synthetic Aperture Radar Technology

Introduction: David Nikolaus Perkins, an accomplished inventor based in Albuquerque, NM, has made significant contributions to the field of synthetic aperture radar (SAR) technology. With a total of seven patents to his name, Perkins has developed innovative methods for enhancing the detection and analysis of changes in various environments. His work has greatly advanced the capabilities of radar imagery, providing invaluable tools for monitoring human activities and identifying anomalies.

Latest Patents: Perkins's most recent inventions include the patented technologies titled "Apparatus, System and Method for Highlighting Activity-Induced Change in Multi-Pass Synthetic Aperture Radar Imagery" and "Apparatus, System and Method for Highlighting Anomalous Change in Multi-Pass Synthetic Aperture Radar Imagery."

The first patent describes various methods for constructing a differenced change product (DCP) image. In this process, multiple SAR images of a scene are generated from radar signals, which are reflected off the landscape. Coherence change detection (CCD) images are also created, and these images are registered together with their pixel values adjusted via a monotonic mapping function. As a result, the DCP image highlights locations where human activity is likely to have induced changes between two SAR passes.

The second patent focuses on the creation of a statistically-normalized coherence (SNC) image. Similar to the first, it involves generating a series of SAR images and CCD images, which are also registered. Mean and variance values are computed on a pixel-wise basis and combined with a newly received CCD image to generate the SNC image. This innovative approach allows for the identification of locations where anomalous activities are depicted in the new CCD image.

Career Highlights: Perkins has worked with esteemed organizations such as National Technology & Engineering Solutions of Sandia, LLC and Sandia Corporation. His tenure at these institutions has been marked by his commitment to innovation and excellence in radar technology.

Collaborations: Throughout his career, Perkins has collaborated with several talented individuals, including Katherine M. Simonson and Ivan Lizarraga. These partnerships have fostered a rich exchange of ideas and have significantly contributed to the advancement of SAR technology.

Conclusion: David Nikolaus Perkins is a notable figure in the realm of synthetic aperture radar inventions. With a solid portfolio of patents and a history of collaboration with leading organizations and professionals, his work continues to have a profound impact on enhancing our understanding of dynamic changes in various environments. Through his innovative approaches, Perkins exemplifies the spirit of creativity and advancement in the field of radar technology.
