That's true with most radar systems, but the synthetic aperture radar
doesn't have the same limitations of other radar systems. Synthetic aperture
radar is able to resolve very precise details. The "images" that the
synthetic aperture radar generates are fed into computers that "recognize"
the traps greatly reducing the need to switch to spot mode to manualy
"query" individual vehicles.
