چکیده

This paper considers techniques for creating enhanced resolution images from irregular samples, with specific application to imaging from scatterometers. Using previously established irregular sampling theory, and developing the idea of sub-band limited Banach space, we show that frequency content in attenuated sidelobes can be recovered using resolution enhancement techniques, thus taking advantage of the high frequency content of measurements made with imperfect low pass aperture filters. We briefly compare and contrast the performance of additive ART, multiplicative ART and the Scatterometer Image Reconstruction (SIR) (a derivative of multiplicative ART) algorithms with and without noise.

Electro-Optical Design of Imaging Payload for a Remote Sensing Satellite

Remote sensing using small spacecraft arising from multi-objective economic activity problems is getting more and more developed. These satellites require very accurate pointing to specific locations of interest, with high reliability and small latency. The space borne imaging systems always attempted to achieve the highest ground resolution possible with the available technology at the given t...

Image reconstruction and enhanced resolution imaging from irregular samples

While high resolution, regularly gridded observations are generally preferred in remote sensing, actual observations are often not evenly sampled and have lower-than-desired resolution. Hence, there is an interest in resolution enhancement and image reconstruction. This paper discusses a general theory and techniques for image reconstruction and creating enhanced resolution images from irregula...

Object Level Strategy for Spectral Quality Assessment of High Resolution Pan-sharpen Images

Panchromatic and multi-spectral images produced by the remote sensing satellites are fused together to provide a multi-spectral image with a high spatial resolution at the same time. The spectral quality of the fused images is very important because the quality of a large number of remote sensing products depends on it. Due to the importance of the spectral quality of the fused images, its eval...

Scatterometer Resolution Enhancement - Geoscience and Remote Sensing Symposium Proceedings, 1998. IGARSS '98. 1998 IEEE International

AbsrractScatterometers can be effective for large scale monitoring of the Earth’s surface. However, their low resolution can limit the utility of the data. Thus, there is interest in resolution enhancement methods that can create high resolution imagery from scatterometer measurements. In this paper, a brief review of an iterative image reconstruction is presented, and the implications of this ...
