An Exploratory Verification Method for Validation of Sea Surface Radiance of HY-1C Satellite UVI Payload Based on SOA Algorithm

To support the application of ocean surface radiance data from ultraviolet imager (UVI) payload HY-1C oceanographic satellite and to improve quantification level observation technology, authenticity check study UVI was conducted provide a basis for products. The load makes up lack detection capabilities modern remote sensing satellites in band. UVDRAMS (Ultra-Violet Dual-band RadiAnce Measurement System) used verify collected at 16 stations area pupil by establish an effective radiative transfer model identify parameters using seeker optimization algorithm (SOA). measurement system based on SOA validation sea shows that 97.2% incident is contributed atmospheric reflected radiance, only 2.8% real radiation water surface, while high signal-to-noise ratio can effectively distinguish reflectance body. amount standard deviation on-satellite variation, which meets requirements provides new way thinking technology further quantitative research future.
