InSAR is a sophisticated radar remote sensing technique for combining synthetic aperture radar (SAR) single look complex images to form interferogram and utilizing its phase contribution to land topography, surface movement and target velocity. In recent years considerable applications of Interferometric SAR technique have been developed. It is an established technique for precise assessment of land surface movements, and generating high quality digital elevation models (DEM) from space-borne and airborne data. InSAR is able to produce DEMs with the precision of a couple of ten meters whereas its movement map results have sub-centimeter precision. The technique has many applications in the context of earth sciences such as topographic mapping, environmental modelling, rainfall-runoff studies, landslide hazard zonation, and seismic source modelling. Nevertheless new developments are taking place in the application of InSAR for aquatic bodies. We have observed that using SAR Interferometry technique for aquatic bodies with the maximum temporal baseline of 16 seconds for image pairs shows considerable results enabling us to determine the direction of sea surface motion in a large area, estimate the sea surface fluctuations in the direction of sensor line-of-the-sight, detect wave pattern and the sea surface disturbance and whether the water motion is bulk and smooth or otherwise. This paper presents our experience and achievements on this new topic through discussing the facts and conditions for the use of InSAR technique. The method has been examined for Haiti, Dominican Republic, Western Chile and Western Turkey coast areas and inland lakes however ground truth data is needed for final verification. This technique scheduled to be applied in some other sites for which the proper data is available. 1. INTRODUCTION Considerable applications of INSAR have been developed, while one of its applications is high-quality DEM generation from space- Radar remote sensing is accounted for as a new earth observation borne and airborne data with the precision of a couple of ten technology with promising results and future. Its potentials and meters while its movement map results have ordinarily sub- capacities as a strong complementary tool along with other remote centimeter precision over time spans of days to years. (Henderson, sensing techniques are undeniable. In course of the years of = etal. 1998) explorations and examining the new radar technologies, their Satellite-based InSAR began in the 1980s using Seasat data, unique possibilities to comply the needs and answering the although the technique expanded in the 1990s after the launch of questions that the classic optical and thermal remote sensing ERS-1 (1991), JERS-1 (1992), Radarsat-1 and ERS-2 (1995). They techniques have been unable or difficult to tackle has grown the provided the stable well-defined orbits and short baselines expectation that radar technologies can play a key role in bridging necessary for InSAR. The 11-day NASA STS-99 mission in the gaps in this connection. February 2000 used two SAR antennas with 60-m separation to Nowadays, radar remote sensing in general and the Synthetic collect data for the Shuttle Radar Topography Mission (SRTM). Aperture Radar (SAR) technique in particular increasingly show As a successor to ERS, in 2002 ESA launched the Advanced SAR their values and potentials. Radar is a useful tool for land and (ASAR) aboard Envisat. Majority of InSAR systems has utilized planetary surface mapping. (Thompson, et al., 2001) It is a good the C-band sensors, but recent missions like ALOS PALSAR and mean for obtaining a general idea of the geological setting of the TerraSAR-X are using L- and X-band. ERS and Radarsat as well area before proceeding for field work. Time, incidence angle, as Envisat use the frequency of 5.375GHz for instance. Numerous resolution and coverage area all play important role at the InSAR processing packages including IMAGINE-InSAR, outcome. (Colwell, 1983) EarthView-InSAR, ROI-PAC, DORIS, SAR-e2, Gamma, SAR interferometry (InSAR), Differential InSAR (DInSAR) and SARscape, Pulsar, IDIOT and DIAPASON are used commonly. recently emerging Persistent Scatterer (PS) InSAR are the new techniques in radar remote sensing. (Tarikhi, 2010a) By using 2. INSAR AND DEM GENERATION METHODS InSAR technique very precise digital elevation models (DEM) can be produced which privilege is high precision in comparison to the SAR Interferometry is a technique to detect subtle topographic traditional methods. changes enabling to detect minute variations. Its accuracy is InSAR is a sophisticated processing of radar data for combining paramount. A number of DEM generation techniques with synthetic aperture radar (SAR) single look complex (SLC) images different accuracies for various means are used. DEMs can be to form interferogram and utilizing its phase contribution to generated through different methods which are classified in three generate DEM, surface deformation and movement maps and groups that are DEM generation by (i) geodesic measurements, (ii) target velocity. The interferogram contains phase difference of two photogrammetry and (iii) remote sensing. (Tarikhi, 2009) images to which the imaging geometry, topography, surface DEM generation by remote sensing is made in few ways, including displacement, atmospheric change and noise are the contributing stereo-pairs, laser scanning (LIDAR) and InSAR. There are three factors. types of InSAR technique that is single-pass, double-pass and three-pass. In double-pass InSAR, a single SAR instrument passes 85
