Our model makers built a Tactical Airport Surveillance Radar model series for ITT. This particular design is called the TASR-2020.  Using  photo-like images for reference, the majority of the pieces were made out of brass for strength, beauty and longevity. The CNC mill was used  to cut the brass parts which were then soddered together.  The fixed location unit was built mostly of styrene, which is a more flexible, durable material than plexiglass.   The radar dishes were motorized to attract attention at trade shows.
