This paper presents the imaging method applied for moving target tracking by a multistatic ultra-wideband radar system. The imaging method consists of such signal processing phases as raw radar data pre-processing, background subtraction, the fusion of the data obtained by the particular receiving channels of a radar, detection, localization and the tracking itself. In this paper, the particula...

We present the hardware implementation of radar real time processing procedures using a simple, fast technique based on FPGA (Field Programmable Gate Array) architecture. This processing includes different window procedures during pulse compression in synthetic aperture radar (SAR). The radar signal compression processing is realized using matched filter, and classical and novel window function...

see through the wall radar, is a relatively new small range radar that uses electromagnetic waves to detect targets behind wall. because of its symmetry, a conducting sphere is often used as a reference scatterer to calibrate radars. in this paper, to simulate received signal for see through the wall radar, scattering model of a conducting sphere in free space is presented. then using a dielect...

This paper aims to outline some interesting properties of Nested Wigner Distributions. A number of features of such functions that can be useful in radar signal analysis are demonstrated with suitably simulated examples.

T he automobile has played an important role in shaping our society for the past century, and signal processing is playing an increasingly substantial role in shaping smart vehicle technologies today. Part 2 of the special section on signal processing for smart vehicle technologies provides additional six articles, complementing those in Part 1, which was published in the November 2016 issue of...

In radar and sonar signal processing it is of interest to achieve accurate estimation of signal characteristics. Recorded pulse data have uncertainties due to emitter and receiver noise, and due to digital sampling and quantization in the receiver system. It is therefore important to quantify these effects through theory and experiment in order to construct “smart” pulse processing algorithms w...

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. It involves the description of the basic scanning method, data preprocessing and c...

High-frequency (HF) surface wave radars provide a unique capability to detect targets far beyond the conventional microwave radar coverage. This capability also could contribute to the development and improvement of Tsunami Early Warning Systems. This paper presents the system design and introduces the key signal processing methodologies that enable the HF radar to provide early warning of the ...
