Interferometric Sar

Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) can improve interferometric coherence and phase quality, which has good application potential. With the development of the Mini-SAR system, Unmanned Aerial Vehicle borne (UAV-borne) PolInSAR systems became a reality. However, UAV-borne PolInSAR is easily affected by air currents and other factors, which may cause large motion errors and polarization distortion inevitably exists. However, there are few pieces of research which are about motion compensation residual error (MCRE) and polarization distortion effects on PolInSAR. Though the effects of MCRE on Interferometric SAR (InSAR) and polarization distortion on PolInSAR were studied, respectively, these two parts are independently modeled and analyzed. In this paper, a model that simultaneously considers the effects of these two kinds of errors is proposed, and simulation results are given to validate the model. Then, a quantitative analysis based on a real Quadcopter UAV PolInSAR system is performed according to the model, which is valuable for system design and practical application of the UAV-borne PolInSAR system.

AbstractSonar imaging has numerous applications in the underwater domain. High-resolution sonar images are useful in marine research, underwater construction work, offshore oil and gas, search for objects, and in the military sector. Common in many applications is the desire for higher resolution, better image quality, longer range, and smaller hardware footprint. Synthetic aperture sonar (SAS) technology can improve resolution and/or range substantially compared to traditional technology. Recent developments in SAS make this technology more available now. This paper gives a review of SAS technology and shows example of SAS applications. The paper lists the current state-of-the-art and the future trends of SAS.
