Abstract
A method of operating a continuous wave radar to derive range information as well as Doppler information is described. The transmitted signal is frequency modulated at a low modulation frequency and peak deviation so that range ambiguities are effectively avoided and echo signals may be processed at a relatively low intermediate frequency, thereby allowing echo signals from clutter to be more effectively rejected and echo signals from a moving target to be correlated.
