In this paper, a new millimeter wave 3D imaging radar is proposed. The user just needs to move the radar along a circular track, and high resolution 3D imaging can be generated. The proposed radar uses the movement of itself to synthesize a large aperture in both the azimuth and elevation directions. It can utilize inverse Radon transform to resolve 3D imaging. To improve the sensing result, th...

This paper looks at 3 different types of radar imaging systems; synthetic aperture radar (SAR), through-the-wall radar, and digital holographic near field radar. Each system surveyed experiments that improved the quality of the resulting image. It was found that each radar system has specific problems. The digital holographic near field radar imaging system was studied the closest. Findings rev...

polarimetric synthetic aperture radar (pol.-sar) allows us to implement the recognition and classification of radar targets. this article investigates the arrangement of scatterers by sar data and proposes a new look-up table of region (ltr). this look-up table is based on the combination of (entropy h/anisotropy a) and (anisotropy a/scattering mechanism α), which has not been reported up now. ...

In this review paper, we provide a comprehensive review of rec...

Two dimensional (2D) radar coincidence imaging is an instantaneous imaging technique which can obtain 2D focused highresolution images using a single pulse without the limitation to the target relative motions. This paper extends the imaging method to three dimensions. Such a three-dimensional (3D) radar imaging technique does not rely on Doppler frequency for resolution and has an extremely sh...

This paper applies the principle of radar polarimetry to a synthetic aperture frequency-modulated continuous wave (FM-CW) radar and presents results based on two-dimensional (2-D) full polarimetric imaging. It is shown that the polarimetric target reflection coefficients obtained by the synthetic aperture FM-CW radar are elements of a Sinclair scattering matrix, although the coefficients are de...

all-weather, dayand-night imaging capability for mapping the Earth’s surface. Through interferometric synthetic aperture radar (InSAR) technique, radar imagery can be used to map Earth surface characteristics and measure land surface deformation at an unprecedented precision and spatial resolution. This article introduces the basics of radar and InSAR imaging, summarizes the revolution of InSAR...

Synthetic Aperture Radar (SAR) imaging is an expensive endeavor. It can be difficult for universities, small business, or individuals to experiment with SAR imaging and algorithm development on a low budget. For this reason, a uniquely inexpensive solution to FrequencyModulated Continuous-Wave (FMCW) radar was developed and then utilized as an ultra low cost SAR imaging system. This unique appr...

The Super-SVA algorithm has been shown effective for improving the resolution of microwave synthetic-aperture radar (SAR) In this paper we review the Super-SVA algorithm and demonstrate its application to optical imaging systems using coherent laser illumination. Examples of such imaging systems include heterodyne-array imaging, holographic laser radar, laser syntheticaperture radar, coherent p...
