WebA chirpis a signalin which the frequencyincreases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirpis used interchangeably with sweep signal.[1] It is commonly applied to sonar, radar, and lasersystems, and to other applications, such as in spread-spectrumcommunications (see chirp spread spectrum). Webcompression coefficient for the pulse compression when simulating the pulse compression. It is easy to work out the chirp signal s pulse compression coefficient, which can be achieved by conjugating and overturning the ideal chirp signal. The steps for simulation of chirp signal s pulse compression using Matlab are shown as follows.
