Resumen:Conference Title: 2018 Eighth International Conference on Instrumentation & Measurement, Computer, Communication and Control (IMCCC)Conference Start Date: 2018, July 19 Conference End Date: 2018, July 21 Conference Location: Harbin, ChinaIn this paper, we firstly analyze some disadvantages in current spaceborne synthetic aperture radars (SARs). Because the traditional processing pattern of "satellite data acquisition-ground station receiving and processing-data distribution-professional application" can't satisfy the time-effective flexible requirements of environment and disaster emergency response monitoring, this paper proposes the concept of "intelligent sensing high resolution spaceborne SAR system", design the system framework with intelligent remote sensing and onboard real-time data processing ability, which consists five modules: (1) afore-looking pre-judgment module for space electromagnetic environment and observation scene; (2) an adaptive transmitted signal formation module; (3) an adaptive antenna reconfiguration module; (4) an adaptive returns data sampling module; (5) an onboard real-time data processing and analysis module. It also introduces the work process flow involved. Then, we conclude four key technologies, they are: (1) observation scene afore-looking pre-judgment technology; (2) adaptive SAR payload parameter setting technology; (3) adaptive transmitted signal formation technology; (4) onboard real-time data processing and information generation technology.
