Drone radar facilitates agricultural monitoring
In agriculture, drones distribute seeds or fertilizers with precision, saving both time and money. When combined with sensors and artificial intelligence, they can perform remote sensing, similar to satellites and airplanes, monitor large crops, conduct detailed analyses of soil’s chemical elements, and identify issues such as erosion. One of the most advanced techniques in this field, Synthetic Aperture Radar (SAR), has been enhanced by Radaz, a startup founded in 2017 at the University of Campinas (UNICAMP) and now based in São José dos Campos, São Paulo. “It’s an innovative technology with enormous potential to generate a wide variety of products, serving various market segments,” says electrical engineer Hugo Enrique Hernández Figueroa from UNICAMP’s School of Electrical and Computer Engineering (FEEC), who led the team responsible for developing a radar mounted on a small drone. To achieve this, the team had to miniaturize the radar’s electronic hardware and antennas. The id...
