A Method for 3D Reconstruction of ISAR Images Using Impulse-Radio UWB
نویسنده
چکیده
Recently, the use of Ultra Wide Band (UWB) technology has been increasing. This technology makes it possible to obtain high-resolution images of distant objects using microwave signals. A 2D ISAR algorithm was developed for defense and tomography and is used in medical approach. In this paper, the tomography algorithm is studied, using microwave similar to those used in reflection tomography. Threedimensional images were reconstructed using two receiver antennae and one transmitter. The ISAR interferometry configuration was designed as a backprojection algorithm. When compared to 2D imaging, the signal has an elliptical range profile in the 3D observation mode. An elliptical range migration is confirmed in both theoretical and experimental results. Keywords— impulse radio UWB, ISAR image, 3D reconstruction, backprojection

UWB Localization complemented by Impulse Radar
This paper describes a novel approach for 3D localization of an object based on fusion of the UWB radio localization techniques and UWB Impulse Radar ranging possibilities. We present a 3D localization system which includes five base stations and a TAG, and introduce the principles of our localization method. The simulation and experimental results indicate that the UWB technology based localiz...
متن کاملPrecision Near-Field Reconstruction in the Time Domain via Minimum Entropy for Ultra-High Resolution Radar Imaging
Abstract: Ultra-high resolution (UHR) radar imaging is used to analyze the internal structure of objects and to identify and classify their shapes based on ultra-wideband (UWB) signals using a vector network analyzer (VNA). However, radar-based imaging is limited by microwave propagation effects, wave scattering, and transmit power, thus the received signals are inevitably weak and noisy. To ov...
متن کامل3D Reconstruction of the Operating Field for Image Overlay in 3D-Endoscopic Surgery
Building a 3D model of the operating field is the first stage to access the registration of pre-operative surface models in per-operative context. We propose a method to learn the 3D model of the organs observed by a stereoscopic endoscope. This method is general and requires no a priori knowledge of the position of the instruments, whether robotized or manually-controlled, present in the field...

ABTRACT Background: In nuclear medicine, phantoms are mainly used to evaluate the overall performance of the imaging systems and practically there is no phantom exclusively designed for the evaluation of the software performance. In this study the Hoffman brain phantom was used for quantitative evaluation of reconstruction techniques. The phantom is modified to acquire t...
