About Dave Vacanti, Founder
44 Years in Radar and Satellite Communications at Boeing and Honeywell provided me with a wealth of experiences in military and commercial product areas. I was fortunate to always be part of Advanced Technology or New Product Development for my entire career. I had the privilege of starting entirely new radar business area paradigms while I was at Honeywell in the areas of Radar Altimeters, Weather Radar for Aviation and finally wide ranging applications for MMW and Microwave FMCW Phased Array Radars. My most recent inventions focused on Low Cost, Low SWaP FMCW Phased Array radars that made use of novel low cost electronic beam steering methods that are not related to Metamaterials methods.

For many of those same years in Aerospace I have also owned and operated Vacanti Yacht Design LLC, a supplier of boat design and analysis software that I personally created using NURB surface modeling methods. Well over 10,000 boats, kayaks, trawlers, racing sailboats and commercial vessels have been designed and built based on my PROLINES and other software products. I have a strong affinity for both Marine and Aviation applications of my Aerospace Radar and Marine software capabilities. I am bound by proprietary information agreements with my prior employers.
