A synthetic aperture radar (SAR) consists of two logical functions: radar and processor. Although the technology (and the measurement accuracy) has been developed over the years since, the basic underlying principles of the Michelson interferometer still remains at the core of interferometry. (an excellent, slightly more advanced textbook covering theory …
An individual reflecting object contributes reflections so long as it remains illuminated by the radar’s antenna pattern. The radar is an active imaging sensor that looks to the side as it moves along its trajectory and collects reflections from transmissions pulse by pulse, storing these data in memory. (a good general textbook covering theory with a little bit on image interpretation). The principles of SAR interferometry, in particular phase unwrapping and geocoding, are described.

This geodetic method uses two or more synthetic aperture radar images to generate maps of surface deformation or digital elevation, using differences in the phase of the waves returning to the satellite or aircraft. 13‐24 February 2017 1.

; Overview. This four-day short course/CPD module emphasises physical principles, modern radar systems and signal processing techniques (for both civilian and defence applications).. the SAR principles and theory, followed by an overview of established techniques like polarimetry, interferometry and differential interferometry as well as of emerging tech-niques (e.g., polarimetric SAR interferometry, tomography and holographic tomography). Interferometric synthetic aperture radar, abbreviated InSAR, is a radar technique used in geodesy and remote sensing. Synthetic aperture radar interferometry is an imaging technique for measuring the topography of a surface, its changes over time, and other changes in the detailed characteristics of the surface. Synthetic Aperture Radar (SAR) is a microwave imaging system. Several application exam-ples including the associated parameter inversion modeling are provided for each case. Outline • To introduce, study and discuss the concept and fundamentals of laser speckle.
It has cloud penetrating capabilities because it uses microwaves; it has day and night operational capabilities because it is an active system; and its ‘interferometric configuration’, Interferometric SAR or InSAR, allows accurate measurements of the radiation travel path because it is coherent. The first demonstration of using light interference principles as a measurement tool was achieved by Albert A. Michelson in the 1880's by developing the first interferometer.
