Abstract
A radiometer circuit for determining the character of the modulation of a signal received from a radio frequency transmitter. The circuit will determine if the transmission is one of the following classes: continuous wave (CW) frequency modulated CW (FMCW), noise modulated FMCW and noise; or pulse modulated, burt pulse modulated, random pulse modulated, or any pulse modulated noise. A single radio frequency amplifier is used to detect and discriminate between pulsed and CW transmissions.
