Abstract:

The report covers an investigation of the signal distortion which results when long, series-fed arrays are used for communication. It is shown that under certain conditions the antenna array can be considered as a linear filter, the response of which is a function of frequency as well as of spatial coordinates. The distortion accompanying the transmission as measured by the least mean square difference between the transmitter and the received signal is derived. This expression s evaluated for the case of a uniformly excited array and a rectangular bandpass signal spectrum. In the absence of noise, the transmitted signal can be completely recovered in the receiver by employment of the proper linear filter. In the presence of noise, the signal cannot, of course, be completely recovered. However, a technique is investigated for minimizing the distortion in this case by use of a prefilter and a postfilter. Author
