Abstract:
We describe a simple, yet elegant method to provide a full sensory experience that describes the operation of a phased array antenna system. Our method is based on using an audio source that feeds an array of speakers appropriately spaced apart such that when a listener walks around the array, they experience the null points as well as the primary lobe and minor lobes. It is extremely profound for the student to experience a relatively loud tone, and then when moving just a few inches perceives the complete absence of the tone. The apparatus is economical and relatively easy to implement and test as compared to an RF antenna phased array. The ideas presented are applicable to other courses in electrical and mechanical engineering that cover signal processing and acoustics. Student assessment has shown that the proposed method greatly enhances understanding of phased array systems.
