Narrow-band Signature Dual-wavelength Method for Photometric Control and Detection of Well-known Configuration Objects Against the Vegetation Background
The theoretical fundamentals of the proposed dual-wavelength narrow-band method of photometric control and detection of the well-known configuration target against the forest background are outlined. The target is detected by calculating its NIR- and RED- narrowband signatures using the proposed formulas at the wavelength intervals with a width of Δλ, closely adjacent to the “red edge” area in the vegetation reflection spectrum and further comparing these signatures with the relevant vegetation signatures. The proposed method provides for the availability of a priori data on the forest spectral signatures, as well as on the ratio of the forest areas and the target on the generated image.
