Table 4 Main parameters of the 40 m radome before and after compensation (5.7 GHz)
From: Phase Compensation of Composite Material Radomes Based on the Radiation Pattern
Parameters | Max field value E max/dB | Left sidelobe-level L-SLL/dB | Right sidelobe-level L-SLL/dB | Nulling depth ND/dB | Beam width BW/(°) | Phase difference PD/rad |
