| Abstract: | The derivation process of Noise Equivalent Temperature Difference (NETD)
based on the definition of NETD is presented. The influence of related system parameters on NETD
is discussed. Then, the influence of the variation of ambient temperature on NETD is analyzed.
Finally, the MATLAB method for calculating the equivalent temperature difference corresponding
to the same radiant power difference is given. |
