Abstract :
The methods of joint stereo and interferometric synthetic aperture radar (SAR) data processing are described as a means for creation of more accurate surface heights matrix. Both stereo and interferometric methods could supplement each other on some stages of processing flow. The flow schemes for illustration of these approaches and results of RadarSat SAR data processing are presented
