IR and Millimeter Technology moves on
Esteban,
I was thinking the same thing about people on this forum who haven't yet come up with a better idea to try but can only make negative comments. I think this fellow has been found out. I was looking up various searches for millimeter detection (bolometers,radiometers,etc.) and of course came up with alot of demining sites,one of which showed how easily it is to detect them with an Infrared Camera at night. I found a really excellant paper put out by the U.S. FCC entitled "Millimeter wave Propogation:Spectrum Management Implications",Bulletin Number 70. This document is packed with so much easy to understand information with alot of charts showing attenuation vs frequency and conditions. Turns out for 250GHZ for dry conditions the attenuation is about .48db per km and about 5db with humidity in the air. Far as through soil for passive detection it looks like about 3 inches is it. That is identical to the Falcon MD-10 that can be EASILY found using google,so I'm happy with these parameters if I can cobble together a working system however crude it may be compared to the big bucks university with the Phd's designing and building them. Robert old chap,you asked me what I wanted you to do and all's I would ask-no beg- is RESEARCH millimeter technology so you can get an idea of the limitations and capabilities. In the above post I gave a specific title of a cheap booklet by Dr. Paul Dobler from the Integrity Research website. Also do yourself a big favor and type in StarTiger into google and study up. I think your testicles will drop to the ground when you see what the British Aerospace industry has accomplished complete with photographs. Good hunting! Randy |
