Abstract

Synthetic Aperture Radar (SAR) remote sensing has become very attractive in Earth observation applications, since it provides high resolution imaging independent of weather conditions and sunlight illumination. However, the design of a SAR system is still constrained by nadir returns and range ambiguities, which can strongly corrupt the quality of the SAR image, if not avoided. Recently, a novel SAR concept, named waveform-encoded SAR, based on pulse-to-pulse variation of the transmitted waveform and on a dual/multi-focus post-processing, has been proposed in order to cope with these ambiguities. While some implementation issues related to waveform variation are still under analysis, this work investigates a simpler variant, where waveform encoding is replaced by azimuth phase encoding and multi-focus post-processing is always performed. In particular, the range ambiguity smearing and suppression capability of four different azimuth phase codes is investigated as a function of the Pulse Repetition Frequency (PRF). Some investigations based on real TerraSAR-X data simulations are performed to prove the effectiveness of the proposed technique in terms of ambiguity suppression and smearing.
