Course content

Basic properties of electromagnetic waves. Scattering and interection of electromagnetic waves with gases and solid materials in optical, IR and microwave bands. Principles of remote sensing instruments, such as imager, radiometer, scatterometer, lidar, radar, synthetic aperture radar, altimeters. Present and future satellite surveillance systems.

Learning outcome

The course gives a fundamental introduction to the use of electromagnetic waves for remote sensing. The course also reviews current and emerging technologies (radar sensors, optical sensors, THz sensors, passive and active sensors). The course will enable will enable the student the following.

Knowledge:
- have a fundamental knowledge of the physical interaction mechanisms between electromagnetic waves and matter
- understand the principle mechanisms in the wavelength range of UV, optical, infrared, THz, millimeter and microwave region
- have a general knowledge of principles for remote sensing concepts and systems in this region.

Skills:
- understand EM -object interaction mechanisms
- have basic knowledge of remote sensing instruments
- have insight into design methology and basic mathematical formulations.

General competency:
- be able to assess suitability of various remote sensing instruments
- have knowledge of various forms of basic and advanced radar, THz, optical systems.

Learning methods and activities

Lectures at two weeks interval. Excercises and guidance teaching in intermediate weeks. Written exams. The course focusses on physical concepts and overall understanding of implemented systems. Postponed/repeated exams may be oral. The course will be held in English.

Recommended previous knowledge

NTNU subjects TFE4130 Electromagnetic and Acoustic Waves, TTT4120 Digital Signal Processing and TFE4160 Electrooptics and Lasers are relevant, but not compulsory.
General knowledge (- and interest!) of physics and electronics. Any specialised knowledge in microwave systems, electrooptics, laser systems, satellite design, digital signal processing and detection theory an advantage, but no prerequisite.

Required previous knowledge

Basic knowledge of electromagnetics. General knowledge of electronics and electronic systems.
