DEF

A radar having the capability to illuminate several subswaths by scanning its antenna off-nadir into different positions.

CONT

Instead of having the beam sweep along in a continuous fashion, we triggered the TR [transformer-rectifier] modules to electronically wiggle the beam back and forth, perpendicular to the direction of flight. In the radar world, we call this ScanSAR (Scanning Synthetic Aperture Radar), because the beam scans across swath the way an electron beam sweeps across the face of a cathode-ray tube to make a television picture. You point the beam at one spot on the ground for about a tenth of a second, then zip it over to another place and point it there for a while, then you zip it over to a third place, then a fourth. By looking at four such subspots, you can sweep out a much wider swath of data.
