Doppler effect manifests in the form of changing instantaneous frequency (IF) of the received signal of a moving acoustic source. Several parameters characterizing a moving source are inherently embedded in the received IF. Thus, a careful analysis of the IF is required to obtain the source motion parameters. In this paper, we show how the IF captures the source information, such as speed, closest...
Estimating the parameters of moving sound sources using only the source signal is of interest in low-power, and contact-less source monitoring applications, such as, industrial robotics and bio-acoustics. The received signal embeds the motion attributes of the source via Doppler effect. In this paper, we analyze the Doppler effect on mixture of time-varying sinusoids. Focusing, on the instantaneous...
