Application: Systems and methods of nonlinear rf beamforming (Patent ID: US20230344124A1)

Lockheed Martin Corp. has filed a patent for a method of nonlinear RF beamforming that involves receiving a reference RF signal, computing linear beamformed signals, determining frequency content for each signal, selecting a reduced subset of signals, and calculating the minimum element-wise magnitude across this subset. The method further includes computing a FFT of a reference channel signal, determining an amplitude mask ratio, applying a learned polynomial response to create a modified amplitude mask, and using this mask to generate a final beamformed signal through an inverse FFT process.

The system and method described in the patent involve complex signal processing techniques to optimize RF beamforming. By utilizing neural networks and FFT computations, the method aims to enhance the beamforming process by selecting a subset of signals and applying a modified amplitude mask. The patent outlines a detailed process involving linear beamforming, frequency content analysis, and the application of learned responses to improve the final beamformed signal. The use of neural networks and hyperparameters in signal selection highlights the advanced technological approach taken by Lockheed Martin Corp. in this patent application.
