Definition

Passive millimeter-wave (PMMW) imaging is a method of forming images through the passive detection of naturally occurring millimeter-wave radiation from a scene. Although such imaging has been performed for decades (or more, if one includes microwave radiometric imaging), new sensor technology in the millimeter-wave regime has enabled the generation of PMMW imaging at video rates and has renewed interest in this area. This interest is, in part, driven by the ability to form images during the day or night; in clear weather or in lo ....etc

SUMMARY
Passive radar systems that exploit illuminators of opportunity, such as FM radio and television broadcasts, to
detect and track airborne targets have been under development for over a decade. This paper reviews efforts
to add radar imaging and target recognition capabilities to such systems. We discuss recent developments
along two parallel threads:
1) Target recognition via radar cross section (RCS) profiles: In this approach, databases of the RCS of
targets at different incident and observed angles are created using meth ....etc

1.INTRODUCTION
The infantry soldier of tomorrow promises to be one of the most technologically advanced mod¬ern warfare has ever seen. Around the world, various research programs are currently being conducted, such as the United States' Future force Warrior (FFW) and the United King¬dom's Future Infantry Soldier Technology (FIST), with the aim of creating fully integrated combat systems. Alongside vast improvements in protective and weaponry subsystems, another major aspect of this technology will be the abili¬ty ....etc

Stereoscopic Passive Millimeter-Wave Imaging and Ranging

Thomas Lüthi and Christian Mätzler, Senior Member, IEEE



Abstract—

This paper presents the first stereoscopic range measurements
at a wavelength of 3.3 mmand discusses the accuracy of
this new method. The synthesis of passive millimeter-wave imaging
and stereoscopy combines the advantages of both principles, naturally
looking high-contrast images and superior poor-weather performance
(compared to visible and infrared ....etc
