Conventional Beamforming with Fixed Weights - Beam Main Lobe Variations Through Weight Adjustments
Detailed Documentation
In conventional beamforming, fixing the weights allows the beam's main lobe to correspondingly change as the weights are adjusted. This variation can be implemented by defining a weight vector where each element corresponds to a sensor element's amplitude and phase weighting. The beam pattern can be computed using array manifold vectors and weight multiplication, enabling main lobe steering without altering fundamental principles. This approach facilitates beam direction control while maintaining system stability, allowing for expanded analysis and detailed implementation scenarios. Key implementation involves calculating the array response through inner product operations between the weight vector and steering vectors, where weight adjustments directly influence main lobe orientation and sidelobe characteristics.
