Herb Weiss was an instructor at MIT until he became one of the first Research Staff at MIT Lincoln Laboratory in 1951. Twenty seven years later when he retired from Lincoln as head of the Radar Division he was in charge of the R and D teams that developed the DEW (distant early warning) and BMEWS (ballistic missile early warning systems). In addition, there were development programs for the FAA that paved the way for the air-to-air collision avoidance systems, improved beacon tracking, and weather radars. The weather pictures now routine on television are based on the digitally processed range/doppler techniques that were developed at laboratory.
The division of the laboratory that Weiss directed has also been active in many other projects. These include both airborne and ground based radars for the detection of moving personnel in foliage. Laboratory-build equipment with this capability was used in Vietnam. An airborne radar capable of detecting moving vehicles in ground clutter was also developed.
An active development program for the FAA included basic work on the airborne collision avoidance system, beacon data links, improved radar processing, and weather tracking equipment. The colored moving weather pictures shown on TV is one direct result of the range/doppler concepts pioneered at Lincoln.
Weiss has served on the Ballistic Missile Defense Panel of the President's Advisory Committee, the Department of Defense Electronic Systems Advisory Panel and on the FAA Air Traffic Control Advisory Committee. He is a Fellow of the American Academy of Arts and Sciences and the IEEE Editorial Board. He received a Presidential Certificate of Merit for his war-time work for the Air Force and a second Presidential Certificate Merit for his work for the U.S. Navy. In 1954 he received the Air Force Outstanding Achievement Award.
