WebSep 15, 2006 · Binary chirp slope keying (CSK) has an advantage over binary phase-shift-keying (PSK) in the Rayleigh channel, in terms of probability of error (PE) as a function of signal-to-noise ratio (SNR). Clearly, for SNR above about 14.5dB, chirp slope keying performs better than standard phase shift keying in the simulated UWA environment. bonedrumshome https://gmtcinema.com

WebThe experimental results show that the chirp signal improves the signal-to-noise ratio and expands the applicable time-of-flight algorithm. The waveform pulse width after cross-correlation is 1.5 μs, compared with 40 μs before. The time-of-flight uncertainty can achieve 1.03 ns compared to 8.6 ns before. WebDec 10, 2024 · Dechirp processing [ 1] is a most widely-used method in engineering to process wideband chirp signals. This technique converts the chirp signal into a single tone frequency signal via mixing the radar echo with the reference signal to remove the frequency modulation slope, and then performs digital sampling and subsequent processing.

A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications … See more The basic definitions here translate as the common physics quantities location (phase), speed (angular velocity), acceleration (chirpyness).
