Flux Beamforming via Magnitude Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beamforming techniques suffer from undesirable side lobes in the rejection zone, frequency-dependent beam shapes, and distortion of on-beam signals, making them inefficient for applications requiring precise beam control, especially in sound and RF frequency ranges.
Innovation Solution
The method involves generating flux beams by detecting and processing flux signals using a sensor array, where flux patterns and magnitude patterns are created through signal processing techniques such as Fourier transforms, and these patterns are then combined to form a flux beam that minimizes side lobes and maintains beam shape integrity across frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional phased array beamforming techniques are used, then beam directionality is achieved, but side lobes appear in the rejection zone and on-beam signals are distorted
Solution Approach 1:
The patent extracts only the magnitude information from the flux signals while discarding phase information. By using magnitude patterns instead of complete complex signals, the method eliminates the interference that causes side lobes and phase distortion, achieving clean beamforming without harmful artifacts
Solution Approach 2:
Instead of using the conventional approach of adding phased signals to form beams, the patent inverts the approach by using magnitude patterns that are combined through multiplication in the frequency domain. This reverse methodology fundamentally changes how beamforming is achieved, avoiding the side lobe problem entirely
2Object-generated harmful factors
If a large number of sensors are used to reduce side lobes, then side lobe levels decrease, but device complexity and sensor requirements increase
Solution Approach 1:
The patent replaces the mechanical approach of adding more physical sensors with a signal processing substitution. By using magnitude patterns and frequency domain multiplication, the system achieves side lobe reduction through mathematical operations rather than increasing sensor count, significantly reducing device complexity
3Adaptability or versatility
If phased array techniques are used for broadband sound applications, then beamforming is achieved, but beam shape degrades at higher frequencies
Solution Approach 1:
The patent changes the fundamental parameter used for beamforming from phase (which is frequency-dependent) to magnitude (which is frequency-independent). By operating in the magnitude domain and using multiplication instead of addition, the beam shape remains consistent across the entire broadband frequency range without degradation at higher frequencies

AI summary
A flux beam is generated as a function of flux magnitude patterns. A plurality of flux signals is detected via a sensor array comprising a plurality of sensors. A plurality of flux patterns is generated based on the plurality of flux signals, each of the plurality of flux patterns representing a respective one of the plurality of flux signals. A plurality of flux magnitude patterns is generated based on the plurality of flux patterns, each of the plurality of flux magnitude patterns representing an absolute value of a respective one of the plurality of flux patterns. A flux beam is then generated as a function of the plurality of flux magnitude patterns.
