ABSTRACT:
A method and system for absolute measurement of noise power is described. e method is valid at all radio frequencies but is particularly useful above 65 GHz where no other means for making such measurements currently exists. A gas driven shock tube is provided as a primary laboratory standard of high temperature and, hence, noise power. A system and method for comparing a noise source under test to the primary standard in order to provide an absolute measurement of noise power generated by the test source are described.
