The aim of the subject is to gain a systematic understanding of modern telecommunications and remote sensing systems. After describing the systems, it details the role and tasks of the system elements up to the depth of the design. We deal with the main functional elements of radio systems: transmitter, receiver, antenna, radio channel. We deal in detail with the theory of modulations, including extended spectrum modulation. We deal with the description of noise in telecommunication systems and its role in designing. They get to know the basics of EM remote sensing, which is currently used in many areas: air traffic control, vehicle collision prevention, geodesy, cartographic applications, etc. After a general discussion of systems, the subject presents various applications: terrestrial point-to-point microwave links, various radar systems (PSR, SSR, PET, PCL), satellite telecommunication systems, satellite positioning and navigation systems, satellite remote sensing systems. Within the scope of the subject, students acquire skill-level knowledge in the field of design and application of wired and wireless systems and microwave system components. Students of the subject will be aware of the basic operation and structure of radio networks and remote sensing systems, and will be able to design the basic elements of these systems.
