APSAR (The Asia-Pacific Conference on Synthetic Aperture Radar) is an international conference devoted to SAR and radar technology development and applications. With the dramatic increase of the number of operational SAR systems in recent years, there is now a strong demand for more gatherings where the regional SAR and radar communities can share their technical expertise. APSAR provides an opportunity for presenting the latest research and development by experts of SAR and related fields, and is a forum for discussion with colleagues from many countries, from the Asia-Pacific region and beyond. APSAR covers a wide variety of SAR and radar related topics including SAR applications, analysis techniques, signal processing, SAR system design and concepts, and more.
