【 摘 要 】

The paper analyses capabilities of a laser reflection method for remote vegetation monitoring at eye-safe sensing wavelengths in the NIR spectral band and provides a statistical simulation of correct detection and false alarm probabilities to solve the tasks of vegetation monitoring. Shows that at the wavelengths of 1.54 2.03 μm, for example, the laser reflection method of sensing 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. The laser reflection method using two sensing wavelengths in the NIR spectral band can be accepted as a basis of the vegetation monitoring method using a high-flying aircraft.
