Principles and Practice of Remote Sensing

Module Tutor: Dr M. Disney

Module: 15 credits

Department: Space and Climate Physics

This module provides an introduction to the basic concepts and principles of remote sensing. It includes three components:

1. The geometric principles of remote sensing: geodetic principles and datums, reference systems, mapping projections distortions and transformations; data acquisition methods.

2. The radiometric principles of remote sensing: electromagnetic radiation; basic laws of electromagnetic radiation; absorption, reflection and emission; atmospheric effects; radiation interactions with the surface; orbits; spatial, spectral, temporal, angular and radiometric resolution; data pre-processing; scanners. Introduction to radiative transfer, with focus on models of vegetation and terrestrial surface.

3. Active remote sensing and time-resolved signals (Lidar and RADAR): Lidar: lidar principles; types of lidar system; advantages of lidar observations; information content; discrete return v waveform; current and future systems; ground-based lidar. RADAR: RADAR principles; time-resolved signals; the RADAR equation; RADAR resolution; phase information and SAR interferometry; microwave applications.
