The Water Body Suspended Silt Many Angle Polarization Reflection The Quantitative Research Of The Characteristic

The foundation of the remote sensing technology is the description of the characteristic(includes the intensity of the spectrum and the geometry characteristic characteristics ofpolarized characteristic and object itself ) that the electromagnetic wave appears of object. Atpresent, the information that remote sensing utilizes concentrates on the electromagneticintensity characteristic and geometry characteristic mainly, however, polarized informationcan be regarded as another information source with more valuable one dimension of remotesensing, more than one hundred polarized pictures , polarized spectrum information have fullyproved this on the ground brought back from American space agency plane. Compared withnon- polarized information measurement, polarized information measurement can get thecharacteristic information parameters of more easier distinguishing , differentiating ,quantitative goals . For discern getting different ground goal (for instance, ground natural andartificial facility ) , atmospheric aerosol , cloud , snow , water body ,etc. polarized state. Allextremely valuable potential information. Especially the surface with low contrast ratio toreflection radiation intensity, can utilize polarized data effective discernment goal , go onquantitative analysis win valuable remote sensing message goal. The content of the suspended substance is one of the most important water quality indexparameters in the water body. Suspended substance, especially the size including sandquantity influences such optics nature as transparency , turbidity and water color of the waterbody ,etc. directly, influence the aquatic ecological condition and river mouth littoral zone tochange the course towards the silt too, so, the investigation of the silt , to the water quality ofthe littoral zone of river mouth that suspended substance, especially water body suspend, allthere are important meanings in research , coast project , port construction of ground form ,ecology , environment ,etc.. The routine investigation method is to utilize investigation shipsample , analysis piecemeal, investigate slowly , cycle is long. This kind of method can onlybe obtained in time, very dispersed a small amount of data on space distribution. This kinddispersed sample data compare precision with to be very much poor very in whom time, spacedistribution have. Utilize remote sensing of satellites to have the characteristics that greatyardstick moves ahead simultaneously fast. Adopt remote sensing quantitative technology ,especially adopt polarized remote sensing quantitative technology can obtain large materialsincluding sand quantity of water areas of area rapidly, unless it is the instantaneous sex notsynchronous the getting finer extremely, from replying not obtaining cycle of data theshort,can effective monitoring water body distribution and the change not dynamic notincluding sand quantity, overcome the deficiency of the routine method, plan to mend theprecision question of the traditional remote sensing technology again at the same time . Want utilizing satellite remote sensing draw water body suspend relevant message of thesilt effective, must suspend to water body polarized message remote sensing knowledge of silthave deep understanding. On the introduction foundation to existing domestic andinternational polarized remote sensing information, this text has introduced the pluses andminuses of polarized remote sensing and traditional remote sensing first , understand aftercarrying on the knowledge generally. Suspend to polarized spectrum space distribution , waterbody , water body of silt silt polarized physics mechanism of spectrum carry on deepexposition and then. Pure polarized characteristic, absorb and scattering coefficient of water,suspend polarization of silt reflect space distribution law , optics nature , absorb and scatteringcoefficient ,etc. of spectrum for instance. All these polarized remote sensing analysis andabstraction of the characteristic parameter of the silt to suspending lay the foundation.Accumulate experience for t...
