Bandwidth phenomenon of spatial smoothing techniques

The bandwidth of signal sources related to the decorrelated performance analysis of the spatial smoothing technique is derived. The relationships between time delay and phase delay based on the concepts of random processes are discussed. The decorrelation performance analysis of spatial smoothing for real multipath sources is discussed. The optimal subarray number corresponding to various signal bandwidths of spatial smoothing is also suggested. The simulations based on the time delay model are shown.<<ETX>>
