Airborne SAR system with real time processor

NEC has developed an advanced airborne real-time synthetic aperture radar (SAR) system. The system has already been delivered to some customers and is in operation. By implementing all, necessary processing functions by software, such as yaw-steering compensation and multi-resolution mode with pre-summing, we have been able to eliminate several important hardware components such as mechanical yaw steering system and data reduction filters. This fully digitized and soft-ware oriented SAR architecture gives significant flexibility to the system, without compromising its performance. This radar system consists of SAR antenna equipment, an RF rack, and a control parts rack.
