Hello,
I am taking some measurements in the anechoic chamber which is placed inside a Faraday's Cage, using a radiometer. The signals that we are dealing with a very low power signals i.e. something from a heat source. There are two different things happening:
P.S. (These measurements are compared with the Hot and Cold references )
1) When the heat source is placed outside the anechoic chamber and allowed to cool down a good variation is observed, depicting the cooling of the tile. But the tile appears to be much hotter than expected and the trend lies outside the references used making us feel that the antenna is picking more signals than expected.
2) When the heat source is placed inside the anechoic chamber and allowed to cool down, no variation is observed. These measurements lie within the references.
All I want is that the variation to be observed within the reference levels and not any hotter.
Any Suggestions or reference material is welcome.
Thanks in advance.
