WebJan 6, 2024 · In applications of radar, the nulling beampattern is expected to have the following properties: (1) Preserving the gain at the desired direction, (2) Maintaining main beam shape to achieve a satisfactory angular resolution, and (3) Limiting the levels at the interference directions to no more than a given level. WebApr 8, 2015 · Subtracting beampatterns obtained for the different lancet rotations studied from the beampatterns obtained for the upright lancet showed numerous local changes (see Fig. 7) with changes in beampattern gain around 10 dB not being uncommon. The prevalence of such large gain changes increased with increasing rotation of the lancet …
Webbeampattern matching design criterion, we consider a new design criterion for sensing, which aims to max-imize the minimum weighted beampattern gain at the sensing angles of interest. Accordingly, by considering each type of communication receivers, we formulate two ISAC design problems, with the conventional objective of
