Body explains two kinds that generate and Lu Yuan is generated on the spot.
The basis of Ocean Color Remote Sensing first is that water body Optical characteristics and water spectral pattern measurement are analyzed.Its reason has two
Aspect: first is that the water body signal contribution in the resultant signal that water colour sensor receives is smaller (generally less than 10%)；Second is that water colour
Remote-sensing inversion algorithm is sensitive to the application condition of Remote Sensing Reflectance.Water body optical signature mainly includes Inherent Optical Properties (IOPs)
With apparent optical properties (AOPs).Inherent Optical Properties are only determined by the physical characteristic of water body itself, not with incident field

It rings, at this point, the water spectral signal of spectrometer measurement can indicate are as follows:
Lμ=Lw·+ρf·Lsky
To be comparable the water spectral measured under different time, place and atmospheric conditions, need to measurement
As a result it is normalized.So-called normalization is the surface that the sun is moved on to measurement point, removes atmospheric effect.Water surface incidence spoke
Illumination Ed(0+) can be by the reflection L of measurement standard versionρIt obtains:
Ed(0+)=π Lρ/ρp

The acquisition of remote sensing estimation model, Remote Sensing Reflectance has important application value.When measuring Remote Sensing Reflectance, as long as measuring instrument
Device is stable, the linearity is good (or signal amplitude when measurement standard plate and water body is close), then only need to strictly be marked to on-gauge plate
Determine to thus greatly reduce the workload of instrument calibration without strictly demarcating spectrometer.
By the definition R of Remote Sensing Reflectancers=Lw/Fd(0+), Remote Sensing Reflectance is obtained finally in conjunction with above formula:
In formula: Lμ、Lsky、LρMeasuring signal when respectively spectrometer is towards water body, sky and on-gauge plate.
Single channel spectrometer measurement method based on water oscillation needs to follow very strict observation aggregation specification,
The in-site measurement experience of profession is needed in actual mechanical process, it is more demanding to the measurement capability of Observation personnel.And due to observation
The difference of experience, the data that different Observation personnels obtain will appear inconsistent situation.The rule of single channel spectrometer field observation
Model requires relatively high.
