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
