Millimeter wave radar with clutter measurements

IEEE Aerospace and Electronic Systems Magazine, 2003
A portable millimeter wave test radar system, also suitable for battery operation, gives interesting possibilities for clutter recordings at hard-to-reach sites. The designed system covers all common radar frequencies from the Ka- to V-bands and enables spatial detection of targets or clutter elements within an adjustable time gate, whereby spatial ...

A millimeter-wave radar for train application

Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat. No.99EX257), 2003
A millimeter-wave radar using a spread spectrum technique for train applications has been developed in the 60 GHz band. This radar measures the distance, velocity, azimuth angle, and the magnitude of received signal of each target. The methods for detection are described in this paper. In the experiment, the radar detected the linear shape of trains.

Millimeter Wave Radar Technology

2020
Radar is the abbreviation of ‘Radio Detection and Ranging’. It means to detect and estimate distances via the electromagnetic waves. The millimeter wave is an electromagnetic wave that lies between the infrared light wave and the microwave frequency band. Different classification methods are applied on the different classes of the millimeter wave radar.

Millimeter-wave noise radar tomography

2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016
SAR tomography based upon MIMO concept with channels time-division is described and some results of its experimental validation using Ka-band ground based noise waveform SAR are presented. Two different linear synthetic apertures have been used for both transmit and receive antennas oriented in vertical and horizontal directions, respectively.
