This leads ultimately to a discussion of spatial beam forming using such systems as difar, vertical line arrays, and towed arrays. A study of correlation methods as applied to random noise lead to a discussion of oceanic ambient noise in both temperate and polar seas and the detection of signals in noisy environments. The physics of passive and active sensors operating in the visible, infra-red and microwave is discussed, as are the algorithms necessary to transform sensor data into geophysically meaningful output, such as land elevation vegetation index, sea surface temperature, wave height and wind speed. Remote sensing of solid surfaces is discussed to illustrate the applicability of modern sensor systems or terrestrial environments. Processing and analysis of remotely sensed imagery is discussed to lead the students to an understanding of how to extract information on oceanic and terrestrial features and conditions using modern professional computational techniques.
Emphasis is placed on the use of remotely sensed data for tactical and strategic purposes.
