chirp modulation meaning

[Electronics]
A form of modulation in which the frequency of a signal is deliberately changed in a systematic way. Used in some radar systems.

Examples

1. In binary chirp modulation, binary data is transmitted by mapping the bits into chirps of opposite chirp rates.
2. 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.
