Interferometric synthetic-aperture radar (InSAR)
2007Geodesists are, for the most part, a patient and hardworking lot. A day spent hiking to a distant peak, hours spent waiting for clouds to clear a line-of-sight between observation points, weeks spent moving methodically along a level line — such is the normal pulse of the geodetic profession.

Interferometric Synthetic Aperture Microscopy: Microscopic Laser Radar
Optics and Photonics News, 2010Using instruments from optical coherence tomography and the principles of synthetic aperture radar, researchers have developed a new method for reconstructing 3-D optical images. Doctors may soon be able to use this approach as a noninvasive diagnostic tool in clinical settings.

Interferometric synthetic aperture radar for terrain mapping
1995 International Conference on Acoustics, Speech, and Signal Processing, 2002The paper describes a new technique for topographic mapping using an interferometric synthetic aperture radar (IFSAR). The IFSAR utilizes microwave interference for precise measurement of small linear displacements related to the surface topography. It is similar to a traditional SAR system except that it has two receive antennas (with essentially the ...

Advanced operation mode techniques for an interferometric Synthetic Aperture Radar
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Synthetic Aperture Radar (SAR) operating at Ka-band frequency is increasingly being considered for spaceborne applications. The benefits are seen in the compactness of the instruments, the high bandwidth and resolution. Besides this the high carrier frequency facilitates single-pass interferometry by allowing for an accommodation of all transmitters ...

Correlation of oceanographic signatures appearing in synthetic aperture radar and interferometric synthetic aperture radar imagery with in situ measurements [PDF]
Journal of Geophysical Research: Oceans, 1997 Synthetic aperture radar (SAR) imagery collected over the continental shelf near Cape Hatteras, N. C., is analyzed in conjunction with shipboard hydrographic and current measurements. The SAR measurements were made over a 2‐hour period on June 20, 1993, in both standard mapping mode and interferometric synthetic aperture radar (INSAR) mode from a NASA ...

Motion compensation for airborne interferometric synthetic aperture radar [PDF]
, 1994 Airborne SAR interferometry has the potential to provide topographic data with a precision of the order of one meter. However, to generate data accurate to this level it is essential to measure and compensate for the antenna baseline motion. Conventional motion compensation techniques and their errors are analyzed and extended to the two channel ...

YINSAR: a compact, low-cost interferometric synthetic aperture radar
IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 1998Synthetic aperture radar (SAR) has proven useful for many different applications. Many more applications would be possible with a low-cost instrument. To address this need, BYU (Brigham Young University) has developed YSAR and YINSAR. These compact, low-cost systems are operated from four or six passenger aircraft.
