Introduction toSynthetic Aperture Radar Systems for Small Aircrafts: Data Processing Approaches
The synthetic aperture radar (SAR) is considered now as the most effective instrument for producing radar images of ground scenes with a high spatial resolution. The usage of small aircrafts as the platform for the deployment of SAR systems is attractive from the point of view of many practical applications. Firstly, this enables for a substantial lowering of the exploitation costs of SAR sensors. Secondly, such solution provides a possibility to perform a rather quick surveillance and imaging of particular ground areas. Finally, the progress in this direction will allow for a much wider application of SAR sensors. However, the formation of high-quality SAR images with SAR systems deployed on small aircrafts is still a challenging problem. The main difficulties come from significant variations…
