Abstract

The goal of the project is the working out of a multichannel spectrometric system in the visible and near infrared bands of the electromagnetic spectrum for remote sensing with the following purposes: recognition of main land covers (soils, natural and agricultural vegetation, water areas); state assessment of the studied objects. The multichannel spectrometric system is designed to measure the reflected by ground objects solar radiation in the visible and near infrared range of the electromagnetic spectrum on board of a remotely-controlled airborne platform (helicopter). The measurements will be performed in a main working regime - nadir, helicopter velocity – up to 20 km/h, height – up to 1000 m (optimal 200 m), flight duration - up to 30 min. Components of the system are: multichannel spectrometer; digital camera (optional); data control on-board system; onboard power supply device; fitting elements for installation on board; ground-based computing system for storage and processing of spectrometric data. Technical specifications of the spectrometric system are: spectral VIS-NIR range (450-900) nm; number of spectral channels 128–64; channel location even; spectral resolution (3-10) nm; spatial resolution (1-25) m²; CCD line elements 2048; dynamic range of the system 4 x 104 and per scan 2000:1; exposure time (3-60) ms; measurement flight duration (10-30) min. Main tasks are investigation of the relationships between the reflectance and biophysical features of the studied objects; development and validation of spectral-biophysical models for estimation of land cover parameters; soil state assessment (type, moisture content, surface texture); vegetation state assessment (type, phenological and growth parameters, detection of stress situations) and emergency response.
