Microwave imaging of aircraft

Proceedings of the IEEE, 1988
Three methods of imaging aircraft from the ground with microwave radar with quality suitable for aircraft target recognition are described. The imaging methods are based on a self-calibration procedure called adaptive beamforming that compensates for the severe geometric distortion inherent in any imaging system that is large enough to achieve the high

Confocal Microwave Imaging

2016
Radar breast imaging (RBI) involves the illumination of the breast with a microwave pulse. If a tumour is present, backscattered radar signals are generated due to the dielectric contrast between normal and tumour tissue at microwave frequencies. These backscattered signals are processed by an RBI beamformer to identify the presence and location of any

Microwave System for Head Imaging

IEEE Transactions on Instrumentation and Measurement, 2014
A wideband microwave system for head imaging is presented. The system includes an array of 16 corrugated tapered slot antennas that are installed on an adjustable platform. A switching device is used to enable the antennas to sequentially send a wideband 1-4 GHz microwave signal and capture the backscattered signals.

An imaging microwave radiometer†

International Journal of Remote Sensing, 1983
Abstract The phase A study of an imaging microwave radiometer (IMR) has been completed, for ESA, by a team of contractors led by BAe. The instrument design which was established during this study is described in this paper. The IMR would be able to measure the intensity of radiation in the microwave band at a number of specific frequencies.

Superhigh image resolution for microwave imaging

International Journal of Imaging Systems and Technology, 1990
AbstractAlgorithms for extrapolating the scattered field along the frequency direction and the azimuthal direction are developed and analyzed. Their effects on the image resolution for polar format processing and rectangular format processing are discussed.

A Numerical Approach to Microwave Imaging

18th European Microwave Conference, 1988, 1988
A numerical approach is proposed that aims to detect, by means of interrogating microwaves, the locations, shapes, and dielectric properties of unknown bodies inside an investigation volume. The integral vector equation of electromagnetic scattering is numerically inverted by the moment method in terms of the distribution of the equivalent electric ...

Microwave imaging excavator

Second International Conference on Detection of Abandoned Land Mines, 1998
MIcrowave Imaging eXcavator (MIIX) is based on transmitting and receiving antennas mounted within a cylindrical auger, a stepped frequency CW transmitter/receiver, and an artificial neural network (ANN) imaging processor, all controlled by a small computer.

Passive Microwave Imaging

2009
Although the theme of this book is radar remote sensing, imaging with passive microwave is a complementary technology that warrants an introduction to identify its role alongside radar. This chapter lays the framework for passive microwave imaging, drawing in part from the scattering treatment developed for imaging radar in Chapt ...

Microwave imaging and microwave induced thermoacoustic tomography

2015 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS), 2015
Breast cancer imaging by microwaves has been investigated intensively over the past two decades due to the potentially high electrical contrasts between malignant tumors and normal breast tissue, but so far clinically successful systems have been rare.
