Processing of signum coded SAR signal: theory and experiments

A synthetic aperture radar raw signal which is passed through an ideal limiter is considered. Only the information about the zero crossings is provided because of this process. The output signal is processed in the conventional way. It is then sampled at a rate consistent with the original bandwidth. The image does not exhibit any applicable degradation. The full theory of the operation of this signum coded synthetic aperture radar is provided, as well as a number of confirming experiments
