All this talk about interferometry and metrology (the science of weights and measures) on SRTM sounds great. What other applications are there?
The techniques of interferometry and metrology are used in a wide variety of applications in industry and the sciences. Some particularly useful applications of long baseline interferometry in the space sciences include the use of very-long baseline radio and laser interferometry to study black holes and other objects of astrophysical interest. Some spaceborne examples of this include ARISE and LISA. And if SRTM’s goal of mapping most of the Earth isn’t ambitious enough, there are many upcoming JPL projects in Optical and Infrared Interferometry. The ultimate goal is to someday use huge spaceborne infrared interferometers to image Earth-like planets in other solar systems.
