Abstract:

Digital computer simulation is utilized to study the effects of multi-mode wave interference on the scanning mode of a CDAA. Emphasis is placed on the error induced in the computed direction of arrival of the primary signal by a single interfering signal. Sixteen simulations were conducted in which various signal and system parameters were varied the results show the individual effect of each of these parameters on the induced error. Error spread for the sixteen simulations was found to vary from 0.11 to 12.97 degrees. Author
