- To provide knowledge and understanding of the basic concepts, principles and applications of remote sensing, particularly the geometric and radiometric principles;
- To provide examples of applications of principles to a variety of topics in remote sensing, particularly related to data collection, radiation, resolution, sampling, mission choices.
- To introduce the principles of the radiative transfer problem in heterogeneous media, as an example application of fundamental principles.
- To provide some background to remote sensing organizations and policy through seminars.
The module will provide an introduction to the basic concepts and principles of remote sensing. It will include 3 components: i) geometric principles of remote sensing: geodetic principles and datums, reference systems, mapping projections distortions and transformations; data acquisition methods; ii) radiometric principles remote sensing: electromagnetic radiation; basic laws of electromagnetic radiation; absorption, reflection and emission; atmospheric effects; radiation interactions with the surface, radiative transfer; orbits; spatial, spectral, temporal, angular and radiometric resolution; data pre-processing; scanners; iii) time-resolved remote sensing including: RADAR principles; the RADAR equation; RADAR resolution; phase information and SAR interferometry; LIDAR remote sensing, the LIDAR equation and applications.

3 hour unseen examination, which takes place at the start of Term 2.
The course is based upon lectures, with occasional seminars provided by outside speakers from industry, government etc.
At the end of the course students should:
- Have knowledge and understanding of the basic concepts, principles and applications of remote sensing.
- Be able to derive solutions to given quantitative problems particularly related to geometric principles, EM radiation, LIDAR and RADAR systems
- Have an understanding of the trade-offs in sensor design, orbit, resolution etc. required for a range of applications
- Have an understanding of the propagation of radiation transfer in vegetation, and be able to explain the problem, and propose mathematical solutions
