Abstract

In this paper we want to discuss possible applications of the technology presented in [1], [2], [3]. In particular the use of radar micro-Doppler paired with sine-sweep measurements will be shown to be a powerful method to retrieve the mechanical response of an electro-dynamic loudspeaker, as well as a versatile End Of Line (EOL) classifier algorithm.

The article shortly summarizes the theory behind micro-Doppler applied to loudspeakers in section 2, showing how to interpret correctly the radar signals in a more realistic scenario for both sinusoidal analysis and exponential sine sweep. In Section 3 the radar based mechanical characterization of the speaker will be introduced. For all these analyses, a sampling frequency fs = 22kHz is considered.
