We investigate passive radar imaging of aircraft using reflected TV signals. We apply a Smoothed Pseudo WignerVille Distribution (SPWVD)-based SAR imaging algorithm to two different scenarios. In the first simulation, multistatic VHF-band dataset generated by Fast Illinois Solver Code (FISC) is used. In the second simulation, a more realistic simulated passive radar dataset is used. A set of in...

at first, ground-based circular strip-map synthetic aperture radar (gb-csmsar) and its capabilities is introduced and the received signal model, 2-d frequency spectrum and the azimuth and range resolutions are derived and compared with the linear motion strip-map sar resolutions. because of the stability of the path and speed of antenna in gb-csmsar a frequency domain imaging algorithm is sugge...

Understanding the unusual radar scattering characteristics of sand dunes is necessary in the analysis of radar images of aeolian landscapes of the earth and of other planets. In this paper we report on airborne radar scatterometer data of sand dunes, acquired at multiple frequencies and polarizations. Radar backscatter from sand dunes is very sensitive to the imaging geometry. At small incidenc...

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...

Radar studies of the atmospheric boundary layer (ABL) have become widespread since the advent of relatively inexpensive and compact profiling radars [Ecklund et al., 1988], termed boundary layer radars (BLR). Arguably, one of the most sophisticated of these type of radar systems is the so-called Turbulent Eddy Profiler (TEP), which was developed at the University of Massachusetts [Mead et al., ...

In this work we review and extend the approach for radar imaging using small, wideband, adaptive arrays by using a ray-tracing algorithm to simulate non-homogeneous environments. This allows the rapid investigation of radar imaging in more realistic environments that might be encountered in practice. We have previously shown that such arrays can be effective for short range backscatter imaging ...

The recent development of the synthetic aperture imaging radar [Brown and Porcello, 1969; Harger, 1970; Rihaczek, 1969], which generates high-resolution surface imagery from an airborne or spaceborne platform, has generated interest in the scientific community for its use as an all-time all-weather remote sensor to study the earth's solid surface, oceans, and polar regions [Bradic, 1967; Waite ...

Sensor networks consist of a number of spatially distributed nodes. These nodes perform measurements and collect information about their surrounding. They transfer data to neighboring nodes or to a data fusion center. Often measurements are performed in cooperation of several nodes. If the network consists of Ultra-Wideband (UWB) radar sensors, the network infrastructure can be used for a rough...

Nonlinear radar exploits the difference in frequency between radar waves that illuminate and are reflected from electromagnetically nonlinear targets. Harmonic radar is a special type of nonlinear radar that transmits one or multiple frequencies and listens for frequencies at or near their harmonics. Nonlinear radar differs from traditional linear radar by offering high clutter rejection and is...
