Abstract
SummaryIn order to meet the needs of the application of optical detection and recognition of ship targets in complex sea environment, based on the full link of optical remote sensing detection, the radiation transmission mechanism of ship target characteristics is analyzed. Then, the radiation characteristics model of ship target, the radiation model of ship target thermal wake, and the radiation characteristics model of sea background are established, and the simulation calculation of focal plane radiation characteristics for sea surface ship target is realized according to the space‐based detection and imaging mechanism; Finally, based on the simulation calculation model, the variation law of ship target radiation characteristics under different sea surface conditions and different imaging time are analyzed, which can provide theoretical basis and scientific guidance for the key index design of Space‐Based Surveillance and detection system and the optimization of target detection and recognition algorithm.
