Numeric Simulations for Sensing through the Wall Radar
نویسنده
چکیده
This paper presents numeric simulations related to sensing through the wall radar technologies. Our computational approaches include the Finite Difference Time Domain (FDTD) algorithm and the shooting and bouncing ray technique (Xpatch). We analyze the radar signatures of the human body and other objects, in free-space and inside a room. The emphasis is on radar scattering phenomenology, with results presented as Radar Cross Section (RCS) and Synthetic Aperture Radar (SAR) images.

Ultra-wideband Radar for Building Interior Imaging
This paper presents both numeric simulations and radar measurements related to through the wall imaging technologies. We present synthetic aperture radar (SAR) images obtained by the Army Research Laboratory (ARL) Forward-Looking Radar system during field experiments and compare those with the results of our Xpatch computer models. We also demonstrate a computational approach based on the Finit...
متن کاملThrough-wall detection of human being with compressed UWB radar data
The technology for through-wall human detection with ultra-wideband (UWB) radar was discussed. Due to the large amount of UWB radar data, compressive sensing theory was introduced and compressed UWB radar data can be collected. The singular value decomposition algorithm was used to acquire the singular values of compressed radar data. The compressed UWB radar data were collected at two statuses...

متن کاملCompressive Sensing Meets Noise Radar
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...
