Beampattern gain

WebNov 21, 2016 · Essentially the MVDR will try to place nulls in the beampattern where the interferers are - so a 3dB width doesn't really tell you anything about the resolution. You can also get strange effects, e.g. you'll get 0 dB gain in the desired look direction, and you'll have a sidelobe level of +10 dB somewhere, because it's trying to place a null in ... 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.
