EE40136 Terrestrial and spaceborne remote sensing systems

Credits: 6
Level: Masters
Semester: 1
Assessment: EX 100%
Before taking this unit you must take EE30120
or equivalent. Aims: To provide an overview of the evolution, current status and possible future development of active and passive remote sensing systems.
Learning Outcomes:
On successful completion of this unit students will be able to (i) describe the main features of active and passive remote sensing systems, (ii) make first order calculations for radar and radiometer systems, (iii) be familiar with rudimentary remote sensing analysis procedures.
Elementary system design and data analysis, taught, facilitated and assessed.
Review of the Earth's neutral and ionised atmosphere. Fundamental concepts of Radiometry. Blackbody and non-blackbody radiation, concept of brightness temperature. Basic theory of radiative transfer, concepts of extinction and emission. Microwave interaction with atmospheric constituents: gaseous absorption, extinction and backscattering from hydrometeors, emission from clouds and rain. Analysis of radiometer systems: total power, unbalanced and balanced (noise injection) Dicke switched systems. Fundamentals of real and synthetic aperture radar systems. Passive radar. Ambiguity functions. Principles and applications of atmospheric and ionospheric measurements using remote sensing techniques. Advanced imaging techniques e.g. tomography and radio occultation.
