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). Webshows through analysis and simulations the effectiveness of Chirp-Slope Keying (CSK) in providing a satisfying performance in underwater communication. The experiment consists of modulating a chirp slope by binary numbers (representing our data). „0‟ is represented by a linear- down chirp and „1‟ is represented by a linear-up chirp .
