Technology of spectrum sampling and its application in four dimensional tracking systems;

The improvement of energy resolution was studied in the digitized measurement of nuclear spectra based on the pules shape sampling and the processing of digital highpass filtering for the data of discrete digital pules.

And through the spectral re-sampling methods, established the SPOT-5 multi-spectrum data inversion model, and the model is applied to SPOT-5 remote sensing image to inversion the concentration of chlorophyll of Kuncheng Lake, and use the modified Tropic State Index to evaluate nutritional status of lake eutrophication level cap.
