Webtime. Depending on the type of chirp, the frequency vari-ation is linear or exponential. Chirp signals [7] have been extensively used in radar and sonar systems [9, 30] to de-termine, among other characteristics, range, velocity, and angular position of a target object. The representation of a linear chirp signal y(t) is shown in Equation 1 ... WebApr 27, 2024 · Cross-correlation is the standard digital signal processing technique for measuring the TOF. It is often simpler in practice to perform the calculation of the cross-correlation in frequency domain. If the frequency domain transmitted and received signals are and respectively, the cross-correlation between them is given by: (2)
