MUSIC is a high-resolution signal-processing algorithm for the direction and location finding using the received signals sampled by the array receiver having several sensors. The MUSIC has been conventionally applied to signal sources located in the far field. We are now proposing a new MUSIC algorithm that is able to highly resolve and make precise estimating for the location finding of short-range sources. The new MUSIC will be used in the diagnosis of the machine and for non-destructive testing, etc. This paper will describe the details and differences between the conventional and the proposed MUSIC, and show these performances for the location finding of the simulated signal sources. Results of the numerical and experimental simulations were included to support our examination, and it is clear that the proposed MUSIC was able to precisely resolve and highly estimate the short-range sources.
