Abstract :
The Shuttle Radar Topography Mission (SRTM) will use C- and X-band single-pass/dual-antenna SAR interferometers to map the Earth´s topography. In order to monitor antenna co-alignment and, hence, coherence, a medium-resolution near real-time onboard InSAR processor for the X-band channels is proposed. The implementation details and the various tricks to achieve the required throughput are described
