This work is devoted to measurement of shifts inside an old Cathedral using a Ka-band Ground Based Noise Waveform SAR (GB NW-SAR). Design of this SAR is based upon synthetic aperture antennas and Noise Radar Technology. The system is intended for small shifts measurement at large objects using differential interferometry technique and it can be used for(More)
There are many applications of radar imaging and radar vision. Such systems can be used for intrusion detection, concealed weapons detection, monitoring of various constructions etc. 3D radar images can give detailed and precise information about spatial distribution of scatterers. Such images can be generated using SAR principle. Conventional SAR uses one(More)
Radiometric monitoring allows us to obtain information about thermal electromagnetic radiation of objects in the chosen frequency band. Imaging of distant targets using their thermal electromagnetic radiation may be implemented with the help of bistatic radiometric systems. These systems are based upon measurement of the time difference of arrival of the(More)
Conventional SAR generates 2D image using combination of range compression and 1D aperture synthesis. The range resolution of such approach is determined by the signal spectrum width, while cross-range resolution is defined by the synthetic aperture length. 2D aperture synthesis implies movement of antenna along 2D aperture and cross-range compression(More)
Current paper deals with radar design obtained by combination of two approaches: stepped frequency radar and noise radar for the purposes of SAR imaging. The idea of operation of such combination is following: instead of single frequency signal a narrowband noise signal is radiated in a stepped frequency radar. The processing is done in the same way as in(More)
The paper is devoted to theoretical and experimental investigation of specific influence of the randomness onto the accuracy of phase measurements made with the help of ground based noise waveform synthetic aperture radar. Noise waveform used in this system ensures high electromagnetic compatibility and interference immunity. Random nature of probing(More)
Current paper deals with radar design obtained by combination of two approaches: stepped frequency radar and noise radar for the purposes of SAR imaging. Motivation for such combination is overcoming of drawback of noise radars such as necessity of using fast ADCs in order to provide high range resolution and drawbacks of stepped frequency radar such as(More)
Detection of small changes in natural formations and human-made constructions is a promising application of synthetic aperture radar (SAR). This paper deals with a specific radar, which is a ground-based SAR using noise waveform. Being fully coherent, SAR provides both phase and amplitude information for every pixel in the mapped area. This gives rise to(More)
