Abstract

The application of aperture synthesis concepts, used for many years in radioastronomy to achieve high image resolution at a reasonable cost, to remote sensing technology is discussed. The electronically scanned thinned array radiometer (ESTAR) is put forward as a viable alternative to improve spatial resolution by an order of magnitude over what is presently achieved by microwave imaging systems that are collecting data from Earth orbit. Future developments in airborne sensor technology and potential spacecraft application are described
