Abstract

The invention relates to a method for designing a satellite-borne SAR internal calibration data processing flow in the technical field of satellite-borne SAR internal calibration data processing. Themethod comprises the following steps: (1) according to the satellite-borne SAR integration testing internal calibration data processing flow, function modules are divided; (2) input and output parameters of the function modules are defined on the basis of the division of the function modules, and data interaction among the function modules is realized; (3) the function modules are developed basedon a MATLAB language function form, and meanwhile standardized packaging is carried out; and (4) the development of the internal calibration data processing flow is completed on the basis of the standardized function modules which have been developed. According to the method, the problem in designing the internal calibration data processing flow during satellite-borne SAR integration testing or ground application processing based on the standardized function modules is emphatically solved; the problem in data interaction is solved; and the requirements of efficient automatic processing are met.

Description

Technical field [0001] The invention relates to the technical field of space-borne SAR internal calibration data processing, in particular to a method for designing a space-borne SAR internal calibration data processing flow. Background technique [0002] Synthetic aperture radar is an active remote sensor that works in the microwave range. It is not affected by factors such as sunshine and weather conditions, and can observe and image on the earth all day and all day, so it has unique application advantages in disaster monitoring, environmental and ocean monitoring, resource exploration, crop yield estimation, surveying and mapping, and military. The irreplaceable role of other remote sensors. [0003] Spaceborne synthetic aperture radar integrated testing generally uses independently customized professional software for internal calibration data conversion and processing analysis, usually using test analysis software. The internal calibration data processing and other content ca...
