THE USE OF LIGHTING TECHNIQUES FOR RAPID REMOTE DETERMINATION OF MOISTURE CONTENT OF SUNFLOWER SEEDS GROWING IN THE FIELDS

The method is proposed and the possibility of instantaneous remote determination of sunflower seed moisture using millimeter – range microwave radiation is experimentally investigated. A laboratory experimental setup was created to measure the reflection coefficient of electromagnetic waves from sunflower inflorescences in the frequency range of 25.86-37.5 GHz. In order to create a mathematical model that takes into account the difference between the reflected signal from the side of the inflorescence with sunflower seeds and the reverse side, experimental studies were conducted on the value of the reflected signal from the sunflower inflorescences on both sides of the plant. Experiments were conducted for inflorescences of different degrees of maturity.
