Microwave Imaging Reflectometry of Corrugated Metal Targets

A Data Focusing method for Microwave Imaging of Extended Targets

This paper presents a data focusing method (DFM) to image extended targets using the multiple signal classification (MUSIC) algorithm. The restriction on the number of transmitter-receiver antennas in a microwave imaging system deteriorates profiling an extended target that comprises many point scatterers. Under such situation, the subspace-based linear inverse scattering methods, like the MUSI...

Development of 3D microwave imaging reflectometry in LHD (invited).

Three-dimensional (3D) microwave imaging reflectometry has been developed in the large helical device to visualize fluctuating reflection surface which is caused by the density fluctuations. The plasma is illuminated by the probe wave with four frequencies, which correspond to four radial positions. The imaging optics makes the image of cut-off surface onto the 2D (7 × 7 channels) horn antenna ...

Microwave imaging of time-varying radar targets

The study deals with the introduction of coherent imaging ideas in the kinetic analysis of systems. It is developed in the radar context and is devoted to the description of general targets exhibiting motion, scintillation and dispersivity. This description is based on a physical model of small independent reflectors which can be moving and non-permanent. The resulting representations are gener...

Microwave Imaging Using SAR

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. ...
