Experimental Estimation of the Propagation Delay Time and Multiple Wave Arrival Direction of the FM Broadcast Wave Using the MUSIC Method

Abstract

In order to evaluate the performance of the vehicle-mounted device, to measure the incoming wave parameters of the real environment is important. Conventionally, there is a high-resolution estimation method such as MUSIC processing using the array antenna. However, the MUSIC algorithm can’t be applied simply to low frequency system such as FM broadcast, because the size of array antennas become too large. In this paper, we have developed the MUSIC method that combines the two antennas and RF recorder. As a result, it is shown that the proposed method is very effective.
