Interferometric Synthetic Aperture Sonar

چکیده
Interferometric Synthetic Aperture Sonar (ISAS) offers the possibility of high resolution, three-dimensional images of objects on the ocean floor. The height of objects is identified from the phase difference between two synthetic aperture images of the object obtained using two receivers separated by a short distance. A central problem is the need to unwrap the phase difference in the presence of noise to obtain an unambiguous height estimate. This paper presents an end-to-end simulation of ISAS processing algorithms. The algorithms presented have been shown to work on real sonar data also.

A Technique for Interferometric Synthetic Aperture Sonar Image Processing
Interferometric Synthetic Aperture Sonar provides a means of obtaining high resolution three-dimensional images of objects on the sea floor. This paper describes a technique for forming images using interferometric sonar data. The technique is novel in the way it combines image co-registration and height estimation. Results of applying the technique to real sonar data are given.
متن کاملAssessment of Shallow Water Performance Using Interferometric Sonar Coherence
Interferometry is used for bathymetric mapping with side scan and synthetic aperture sonars. The principle is based on estimating the time difference between arrivals for two vertically displaced receivers. An important additional feature with interferometric sonar is that an estimate of the signal-to-noise ratio can be derived from the coherence between overlaid data series from the two receiv...
متن کاملBathymetry Reconstruction for a Free-Towed Synthetic Aperture Sonar
This paper discusses bathymetric image reconstruction for a Synthetic Aperture Sonar (SAS) with an emphasis on interferometric phase errors. The effect of misregistration between the receivers is shown to be the dominant source of error and is corrected by estimating the time delay between receivers at each range bin. Results are shown for a simulated seafloor.
متن کاملInterferometric synthetic aperture sonar for high- resolution 3-D mapping of the seabed
96 Abstract: A technique is described and demonstrated for generating high-resolution 3-D images of the objects on the seabed, combining synthetic aperture sonar with bathymetric (interferometric) processing. This has applications in surveying of oil wells, pipelines and shipwrecks, and in defence in mine hunting. It is shown that the technique is very sensitive to platform motion errors, and w...
متن کاملSignal Processing for AUV based Interferometric Synthetic Aperture Sonar
This paper presents signal processing techniques particularly suited for interferometric Synthetic Aperture Sonar (SAS) systems onboard Autonomous Underwater Vehicles (AUV) (or other platforms carrying high grade navigation systems). The signal processing is applied to data collected in a controlled rail experiment at Elba Island, Italy, using a wideband interferometric SAS and an Inertial Navi...
