Class Information
Number: 342/84
Name: Communications: directive radio wave systems and devices (e.g., radar, radio navigation) > Return signal controls radar system > Transmitter > Signal phase or frequency other than pulse repetition frequency (prf) > Function of doppler frequency
Description: Subject matter wherein the radar transmitter frequency shift component of the returned signal which is due to the target velocity as it approaches toward or recedes from the radar.
