Abstract

The invention belongs to the technical field of electronic information and specifically refers to a spaceborne synthetic aperture radar polarized system parameter design method. The invention puts forward the polarized system parameter design method which is aimed at four terminal applications that are respectively polarization object decomposition, land surface classification, military object detection and vegetation height inversion. Polarization system parameters comprise one or more of polarization crosstalk, channel imbalance and system noise. The design method is to establish a correlation model between a terminal application evaluation index and the polarization system parameters. The correlation model includes theoretical model formulas or numerical value transfer relationships. According to the correlation model, polarization system parameter design requirements of corresponding terminal applications can be put forward. The invention provides the polarized system parameter design method for a spaceborne synthetic aperture radar system designer, and that a designed synthetic aperture radar system can provide data service according to application requirements can be ensured.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and specifically relates to a method for designing a polarization system parameter of a spaceborne synthetic aperture radar. Background technique [0002] The images acquired by the full polarization synthetic aperture radar system can reflect the different scattering mechanisms and polarization characteristics of ground objects. Using fully polarized SAR images can be used in many applications, such as polarized target decomposition, surface classification, military target detection, vegetation height inversion, etc. These applications will help people understand changes in the ecological climate environment, resource distribution, and defend territorial security. [0003] Although the polarization technology has obvious advantages, the image acquired by the polarization radar system will inevitably be polluted by the disturbance parameters of the system. The polarization system...
