Radar works pretty well in space, due to the lack of atmospheric dust and clouds absorbing the signal, and the lack of terrain to produce spurious echoes, interference, and to block the line-of-sight. Space may be considered the ideal environment for radar to operate in.
Space-based radar (SBR) is a proposed constellation of active radar satellites for the United States Department of Defense. The SBR system would allow detection and tracking of aircraft, ocean-going vessels (similar to the Soviet US-A program), and potentially land vehicles from space.
Oct 11, 2019 · The Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) mission made available to people worldwide the scientific data used to this day to inform decisions to slow and mitigate climate change.
Jun 24, 2013 · Radar is also active: we transmit radio waves at our targets, then wait for the return echoes. This is unlike passive astronomy, where you wait for light that originated hundreds, thousands, millions, or billions of years ago, or observe photons from the Sun reflected off of objects in the solar system.
How It Worked. Invisible to human eyes, radio waves can penetrate thick and murky atmospheres, and they bounce off of hard surfaces. Cassini’s radar instrument sent radio waves at surfaces and, by recording slight differences in the signal’s arrival time and wavelength back at the spacecraft, the instrument created pictures of the ...
