Abstract:

A circularly disposed antenna arrayradio direction finding CDAARFD system Wullenweber can be used to determine the azimuthal angle of arrival for an incoming signal. Unfortunately, there will always be a certain degree of inaccuracy in the resulting value since not all arriving signals will be perfect single-mode data. This report deals with one possible method of determining when to accept the angle-of-arrival value computed from a SUM pattern of the CDAA. Filtering and cross-correlating the data with an ideal pattern are performed. The resulting cross-correlation coefficient gives a value upon which an acceptance or rejection decision can be made.
