Chirps in radar

WebJan 14, 2014 · For quadrature-modulated radar signals such as FM-chirps, two baseband signals, the I and Q components, feed the external modulator. These two components are generated independently and synchronously by a two-channel AWG or by two properly synchronized single-channel AWGs. Chirp modulation, or linear frequency modulation for digital communication, was patented by Sidney Darlington in 1954 with significant later work performed by Winkler in 1962. This type of modulation employs sinusoidal waveforms whose instantaneous frequency increases or decreases linearly over time. These waveforms are commonly referred to as linear chirps or simply chirps.
