RADARSAT-2 MODEX modes: (a) standard two-channel receive mode, (b) three-channel half-aperture toggle-transmit mode, (c) four-channel 3/4-aperture toggle-transmit mode, and (d) four-channel quarter-aperture toggle-receive mode. Shaded rectangles constitute active antenna panels with different shades representing different channels; down/up arrows represent transmitter/receiver physical center positions, respectively; black down-pointing triangles denote two-way effective phase centers.
