Abstract
The detection of ships and other sea targets is of great significance to sea surface management,national de-fense security,search and rescue,and other fields.Space-borne infrared remote sensing has a wide coverage,which is an effective means to achieve wide-area detection of ship targets.Affected by the diurnal cycle of the solar zenith angle,the temperature difference between the ship and the sea surface changes periodically,resulting in a thermal crossover pe-riod twice a day in the ship detection scene on the sea surface.In this paper,taking the mid-latitude summer and winter sea surface environment as an example,the 24-hour infrared radiation characteristics of the sea surface ship detection scene are established,and a multi-spectrum optimal combination scheme is proposed,which is realized by the detection of dual detection spectrum bands of 3.50-4.10 μm and 10.25-10.75 μm day and night continuous observation with sig-nal-to-noise ratio better than 15.The proposed dual-spectrum detection method provides technical support for the appli-cation of wide-area all-time sea surface target detection.关键词
