Abstract:

Digital simulation is used to study the errors in determining the direction of arrival of signals with the CDAA at the University of Illinois in the presence of large systematic defects in the array. Two types of defects are studied. In one, a sector of the array is assumed inoperative sectors from 21 deg to 63 deg wide are studied. In the other, a larger sector is assumed to have a non-symmetrical distribution of operative and inoperative elements. The results show the error as a function of the azimuth of signal arrival.
