| Popis: | The paper presents a comparative analysis of efficiency to detect vegetation under adverse conditions using a passive optical method and a laser reflection one at the eye-safe sensing wavelengths. A mathematical simulation based on the spectral library of the reflection coefficients of vegetation shows that the laser reflection method (at two eye-safe wavelengths in the NIR band or in the NIR and UV ones) can be good advantage for vegetation monitoring. Sensing at the eye-safe wavelengths of 1.54 and 2.03 μm or 2.03 and 0.355 μm allows us to detect vegetation under adverse conditions with a probability of correct detection close to one and a probability of false alarm ~ second decimal places. |
