Meeting Topic
Our guest speaker for the October meeting will be Walt Zavoli. Walt was a researcher in the Wide Aperture Radar Facility (WARF). This radar was constructed in the 1960’s and at that time was the longest steerable HF antenna ever built. Dr. Zavoli will review aspects of its design and performance and give an overview of the research and technical developments it facilitated. Operating in the HF spectrum, many characteristics of HF propagation were observed and studied.
Biography:
Dr. Zavoli graduated from Columbia University with a BSEE and came to Stanford University to escape New York City and get his doctorate in electrical engineering. He was offered a research assistantship in the Radio Science department to work under Professor O.G. Villard. At Stanford, Dr. Zavoli helped build the Wide Aperature Research Facility (WARF), at the time, the worlds longest HF receiving array. While working on “Over-the-Horizon” radar technology, he became interested in unusual atmospheric noise signatures that he observed. His thesis work involved the study of these unusual atmospherics and their association with severe thunderstorms.
After a decade of working on “Over-the-Horizon” radar technology at Stanford University and later at Stanford Research Institute (now SRI International), he followed the Silicon Valley call and re-joined Ken Milnes, Stan Honey and Dr. Alan Philips who had left SRI to start the high tech start-up, Etak Inc. The team developed the “World’s First In-Car Navigation System” predating GPS and in the process fell into the all-consuming task of digital map making. Etak changed ownership several times, and Dr. Zavoli held many positions over his 26 years with the company, including Director of Research, Vice President of Mapping and Sr. VP for Intellectual Property.
Walt is now, happily retired. He spends his time travelling with his wife, Kris, playing bridge, hiking, enjoying photography, cooking, tutoring math and rooting for Stanford football.
