Syfte

Radio detection and ranging (radar) is one of the most used sensor systems for automatic surveillance of people, machines, and nature. When put on a platform like an aircraft or a satellite, it is often used to form images of the ground and its properties, called remote sensing. The aim of this course is to give an overview of typical radar systems and their operational principles, including scattering mechanisms and wave propagation. Each student needs to perform a design of a radar system for a specific application, demonstrating ability to trade different requirements against each other.

Mål

Kunskap och förståelse

För godkänd kurs skall doktoranden

• using a block diagram, describe the basic function, principles of operation, and interrelationships of the basic units of a radar system
• understand the nature of electromagnetic waves with respect to concepts as wave speed, wave impedance, polarization, coherence, and propagation through layered structures such as the atmosphere, soil, or building materials
• describe different scattering mechanisms at different wavelengths, target sizes, and material properties
• discuss how pulse width, peak power, and beam width affect radar performance
• explain the differences between different types of radar systems, like monostatic and bistatic, active and passive, and pulsed and continuous-wave radar
• be able to choose waveform and detection algorithm for unambiguous and accurate target detection
• describe typical applications in surveillance, unmanned vehicles, remote sensing, imaging etc

Färdighet och förmåga

För godkänd kurs skall doktoranden

• be able to use the radar range equation to estimate the maximum detection distance for a target
• quantify target scattering properties using the concept of radar cross section, using handbook formulas and simulation software
• be able to numerically process real radar data, such as extracting range and velocity from scattered pulses, or producing images from synthetic aperture radar data

Värderingsförmåga och förhållningssätt

För godkänd kurs skall doktoranden apply the acquired knowledge by carrying through a project designing a radar system for a specific application, demonstrating understanding of weighting desired technical performance to implementation cost and time

Kursinnehåll

Radar systems on block level, electromagnetic wave properties and propagation through layered structures, scattering theory and radar cross section, stealth technology, radar range equation, antenna pattern, doppler shift, radar signal processing, synthetic aperture radar, MIMO radar, remote sensing and imaging. The theory is demonstrated with practical experiments, and numerical processing of radar data.
