<p>This radar system makes it possible to collect complete stereo data in a single pass by utilizing an orbiting, side looking, bi-static, synthetic aperture radar. This system utilizes at least two orbiting spacecraft (10-12) in synchronous parallel orbits with each other and separated by a tether (14). A transmitter (18) transmits radar signals (26) to a planet's surface which are reflected back (28,30) and received by two receivers (22), one carried by each spacecraft. When the signals are combined, the layover produces a three dimensional picture in which vertical height information may be determined.</p> |
