Abstract :
The design of a radar altimeter, using synthetic aperture processing to achieve high spatial resolution in measurements of land topography, is described. The radar incorporates several novel features, such as digital generation of the transmit and deramp local oscillator waveforms, which allow very high processing gain to be achieved. Examples of experimental results obtained with the altimeter are also presented.
