Passive Millimeter-Wave


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 da ....etc

Abstract
A Gigabit Ethernet passive optical network (GE-PON)
The GE-PON includes an optical line terminal (OLT), a plurality of optical couplers, and a plurality of optical network units (ONUs). The OLT sets up an active page link and a standby page link in response to a registration request message received over an optical cable. Each of the ONUs is doubly connected with the OLT via the optical cable and is adapted to transmit the registration request message to the OLT, form the active page link with the OLT via the optical cable if it rec ....etc

Active and Passive Voice


In the active voice, the subject of the sentence performs the action:
I aced the exam.
Subject/actor verb object/thing acted on
In the passive voice, the object of the action becomes the subject of the sentence, and
the actor appears in a prepositional phrase, or is absent from the sentence:
The exam was aced (by me).
Subject verb actor/object of prepositional phrase
Use the active voice when the actor s identity is important.
Active: The butler did it. ....etc

Abstract
The need of low-loss substrate materials with stable dielectric performances over a wide frequency range is a strong
requirement when working at millimeter frequencies, where standard dielectric substrates exhibit prohibitive losses. In
this contribution, the authors focus their attention on a polymer material, the benzocyclobutene (BCB), having a low
dielectric constant equal to 2.65, and a low loss tangent, equal to 0.0008 at 1 GHz, with a stable dielectric behavior
over a broad frequency range, up to THz. The use of BCB ....etc

Stereoscopic Passive Millimeter-Wave Imaging and Ranging

Thomas L thi and Christian M tzler, Senior Member, IEE


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 wavelengths), as well
as the pas ....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

PASSIVE MILLI METER WAVE IMAGING

Passive Millimeter Wave imaging is a method of formation of images through passive detection of naturally occurring millimeter wave radiation from a scene

Introduction
All natural objects whose temperatures are above absolute zero emit PMMW radiation.
Millimeter-waves are much more effective (Lower attenuation) than IR in poor weather conditions such as fog, clouds, snow etc..
The amount of radiation emitted in the millimeter-wave range is 10 times smaller than th ....etc
