ADAPTIVE ARRAY ANTENNA NULLING |
摘要 |
An adaptive antenna array employs selective polarization nulling and spatial nulling to receive desired signals in the presence of jamming signals. The desired signals have the same circular polarization, and the array includes at least one antenna element having an opposite circular polarization to null jamming signals having an opposite circular polarization. A gain pattern for the array is selected to minimize signals having the same circular, or linear, polarization. The gain pattern is computed based on jamming signals received when no desired signals are transmitted, or measured based on received desired signals. |
