Chirp frequency response
WebCHIRP frequencies allow you to sweep each pulse through a range of frequencies, resulting in better target separation in deep water. CHIRP can be used to distinctly identify targets, like individual fish in a school, and for deep water applications. CHIRP generally performs better than single frequency applications. WebThe chirp of an optical pulse is defined as the time dependence of its instantaneous frequency. In this picture, it shows the electric field of a strongly up-chirped pulse, where …

WebJan 1, 2013 · In the frequency domain (3) R d ( ω) = H ( ω) S d ( ω). Since the chirp response is known via measurement and both excitations are known, the response to sd ( t) can be obtained as (4) R d ( ω) = R c ( ω) S d ( ω) S c ( ω) = R c ( ω) G ( ω). WebIn many mammals, upward-sweeping frequency-modulated (FM) sounds (up-chirps) evoke larger auditory brainstem responses than downward-sweeping sounds (down-chirps). To determine if similar effects occur in FM echolocating bats, auditory evoked responses (AERs) in big brown bats in response to up-chir …
When the Frequency-Time characteristic is non-linear, the Fourier integral is difficult to evaluate. In such cases, it is possible to resort to an approximation method such as the stationary phase approximation, or to use numerical methods. Often (as in radar applications) a(t) is a slowly varying function of time and th…
