The novel monobeam system also has a tight 90-foot turning radius, making it ideal for city settings. The system's 28-foot cars, which are driven by electric motors to speeds up to 55 miles per hour, can carry as many as 52 passengers.
Trains can have up to six cars.
Returning radar is converted back to 4.3 gigahertz and processed via the lower-frequency equipment. The information from the radar is used to construct a perspective grid display of obstacles in a pilot's flight path. The view is then updated in real time. This display system, said Zalenka, is more accurate than others used in helicopter flight such as digitized terrain maps. The system then produced a database and display that helped the test pilot fly over both flat and moderately rugged mountainous terrain.
