[sci.bio.technology] infrared detection of wildlife

     Hello,
 
          I am a systems engineer (EE) who is attempting to help 
the Kenya Wildlife Service (KWS) and Wildlife Conservation Inter
national (WCI) with a technical solution to one of their more 
difficult problems.  The problem is how to count elephants in a 
rainforest.
          One method that is the current hot topic of debate is 
whether or not infrared detectors would be able to detect the 
presence of an elephant's thermal emissions (at night?) through a 
dense forest canopy.  Since there seems to be no clear proof 
either way we would like to conduct some tests to answer this 
question once and for all. 
     We are considering two tests to be conducted here at the San 
Diego Wild Animal Park.  The first test is simply to determine 
was the frequency of any thermal emissions might be.  Since this 
is not my area of expertise I would like someone out there to 
tell me what type of instrument would be best for this purpose; a 
bolometer, a radiance spectrometer or a radiometer?  Also, do you 
know where I may be able to rent or (preferably) borrow.  The 
second test would be from a small plane with some portable 
instrument capable of detecting emissions of the type indicated 
by the first experiment.  Again, what type of instrument would be 
best suited for this experiment and do you know where I might 
rent or borrow one.   The KWS and WCI have very little money to 
spend on this project so we will have to rent or borrow the 
instrument unless it is very inexpensive.
     Thanks in advance for any assistance you can give.
