Hi, How to calculate brightness temperature of a noise source?

23 July 2024 0 8K Report

Now i am currently working on my lab project. Given the ENR(15dB) of the noise source, antenna gain(20dB), band(75GHz~110GHz), how can i get its equivalent brightness temperature? I think it can be calculated through Planck's law, but i dont know how can i get the spectral radiance of a noise source. Can someone help me? :( :( :(
