UWB radar system facilitates us to estimate positions and shapes of the objects behind the wall. It has a great utilization especially for rescue and security applications. This paper briefly describes all signal processing steps that are required for Imaging of the objects scanned by ultra wideband radar device.

This paper presents a method of imaging a two-dimensional section of a walking person using multiple ultra-wideband Doppler radar systems. By exploiting multipath echoes, we can increase the effective number of radar systems virtually. Although each simple radar system consists of only two receivers, different line-of-sight velocities allow target positions to be separated and located. The data...

In this chapter, we discuss how noise radar systems are suitable for realizing practically the promises of compressive sensing in radar imaging, in general, and in urban-sensing applications, in particular. Noise radar refers to radio frequency imaging systems that employ transmit signals that are generated to resemble random noise waveforms. Noise radar has recently been successfully applied t...

We adapt and apply a recently-developed region-enhanced synthetic aperture radar (SAR) image reconstruction technique to the problem of passive radar imaging. One goal in passive radar imaging is to form images of aircraft using signals transmitted by commercial radio and television stations that are reflected from the objects of interest. This involves reconstructing an image from sparse sampl...

Motion compensation is a crucial step to inverse synthetic aperture radar imaging, and envelope correction is the foundation of motion compensation. Research on envelope correction based on the small-angle imaging model has matured after years of development. However, the small-angle imaging model is not applicable to parameter estimation and imaging of micro-motion targets. According to the ch...

Radar Polarimetry Radar Interferometry and Polarimetric SAR Interferometry represent the current culmination in ‘Microwave Remote Sensing’ technology, but we still need to progress very considerably in order to reach the limits of physical realizability. Whereas with radar polarimetry the textural fine-structure, target orientation, symmetries and material constituents can be recovered with con...

In this paper, through wall moving target tracking by M-sequence UWB radar is described. For that purpose, the imaging method consists of radar signal processing phases such as raw radar data preprocessing, background subtraction, data fusion obtained by receiving antennas of radar, detection, localization and tracking itself, is used. Our paper is focused on last phase tracking. Here, new nonl...

in this paper, an unsupervised method for change detection in the multitemporal multipolarization synthetic aperture radar (sar) imagery is proposed. a matrix distance measure, named symmetric revised wishart is used as a test statistic in order to assess the similarity of two multitemporal multilook polarimetric sar data and a variance-based thresholding algorithm is applied to the test statis...
