SAR system for searching and detecting objects in the forest area, based on UAVs

The report considers the task of radar search and detection of objects hidden from direct optical observation by vegetation. A radar system for remote sensing of the earth remote sensing is proposed, placed on board an unmanned aerial vehicle and using the method of aperture synthesis (SAR) in the VHF frequency band. The report substantiates the choice of technical parameters of the system and its parts, and provides the results of designing a prototype remote sensing system based on an octocopter. Optimal signal processing algorithms using a variational Bayesian approach are proposed.
