The airborne sea detection is facing the problem of high humidity，much cloudy and mist，and the strong reflection from the sunlight and clutter complication，which restricts the capability of the sea detection of photoelectric detection system. According to analyze the requirement of sea detection，the problem of clear imaging is solved through the light field camera，the capacity of all-weather detection is improved through the polarization detection，integration and totalization are advanced through the technology of two dimension optical rotation scanning. The ideas and methods are provided for the system of airborne photoelectric intelligence reconnaissance.
