Radio Frequency Interference Suppression Applied to Synthetic Aperture Radar Data
This paper addresses techniques of Radio Frequency Interference (RFI) suppression applied to Synthetic Aperture Radar (SAR) data. These techniques could also be used to protect radio-astronomical observations from harmful interference. Of the RFI suppression techniques investigated, the notch filter and the Least Mean Squares (LMS) adaptive filter have been implemented and applied to real P-ban...
متن کاملOptical aperture synthesis with electronically connected telescopes
Highest resolution imaging in astronomy is achieved by interferometry, connecting telescopes over increasingly longer distances and at successively shorter wavelengths. Here, we present the first diffraction-limited images in visual light, produced by an array of independent optical telescopes, connected electronically only, with no optical links between them. With an array of small telescopes,...
متن کاملThe Object Detection Efficiency in Synthetic Aperture Radar Systems
The main purpose of this paper is to develop the method of characteristic functions for calculating the detection characteristics in the case of the object surrounded by rough surfaces. This method is to be implemented in synthetic aperture radar (SAR) systems using optimal resolution algorithms. By applying the specified technique, the expressions have been obtained for the false alarm and cor...

متن کاملSynthetic aperture radar interferometry
Synthetic aperture radar (SAR) is a coherent active microwave imaging method. In remote sensing it is used for mapping the scattering properties of the Earth’s surface in the respective wavelength domain. Many physical and geometric parameters of the imaged scene contribute to the grey value of a SAR image pixel. Scene inversion suffers from this high ambiguity and requires SAR data taken at di...
