Etymology

From de- + ramp.

Meanings

1. A process for cleaning up electronic signals such as radar, in which a received signal is mixed with a reference signal in order to highlight differences in frequencies.
   • In the deramp process, the principle of continuous radar with a linearly frequency-modulated wave is applied to a pulsed radar. 2001, Philippe Lacomme, Air and Spaceborne Radar Systems: An Introduction, →ISBN, page 223:
   • The trick with full deramp processing is to mix the echo with a replica of the transmitted chirp signal rather than with a fixed frequency tone (figure 4). 2012, Robin A. Vaughan, Microwave Remote Sensing for Oceanographic and Marine Weather-Forecast Models, →ISBN, page 54:
   • Deramp processing entails mixing (i.e., multiplying) the return signal with two sinusoidal carriers of frequency fc and then low-pass-filtering the two resulting signals. 2003, Ronald G. Driggers, Encyclopedia of Optical Engineering, →ISBN:
