Hi, im Anhang ist ein Antennenarray zu sehen, wobei d01 und d02 Basisvektoren von den Gittern sind. Laut der Beschreibung: The optimal array is designed by arranging the nine antennas on the lattice points in different configurations consistent with the relatively prime integer-multiple requirement and computing the quadratic cost (Equation 1) for each arrangement. Just as for the linear array, utilizing these lattice points and prime integer spacings guarantees an array having a gross error rate independent of frequency and signal angle of arrival. The configuration chosen would be one minimizing the cost while giving the required DOA accuracy with the lowest gross error rate. The configuration shown in FIG. 4 is illustrative of how such a final design would look. Kann jemand dieses Prinzip verstehen (relatively prime integer-multiple requirement)? Gruss Senmeis
