(communications)
A type of modulation in which the frequency of each of a series of pulses is linearly varied in a systematic way.

Sure-Fi signals can travel one mile through obstructions or more than 50 miles line-of-sight by using patented radio technology based on Chirp Modulation. Chirp is a component of a radio signal where the actual signal increases and decreases in frequency, creating a pulse or chirp.
Nonlinear Chirp Scaling Algorithm (NCSA) can also deal with squint signal [1,13-16], however, NCSA is developed based on Chirp Scaling Algorithm (CSA), thus requires that the received echo signal must be in chirp modulation. But in some situations the received signal does not hold the chirp modulation, such as when dechirp-on-receive operation is applied in spotlight SAR [17] or Frequency Modulated Continous Wave (FMCW) SAR mode [18], NCSA will be completely disabled.
