Solution Overview
Problem
Existing array antenna modules in low-orbit satellites are large and signal transmission wiring is difficult, with a single control module struggling to process the vast amount of data efficiently, affecting signal processing and transmission speed.
Innovation Solution
A beamforming module control system with multiple beamforming modules and control modules, arranged in zones, connected through buffers and multiplexers, and controlled via serial and quad serial peripheral interfaces, allowing simultaneous data processing and reduced processing burden on individual control modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single control module is used to control the entire array antenna module, then the device complexity is reduced, but the signal processing speed and transmission speed deteriorate due to the huge amount of data processed
Solution Approach 1:
The patent divides the array antenna module into multiple beamforming module zones, with each zone controlled by a separate control module. This segmentation allows parallel processing of signal data across multiple control modules, significantly improving signal processing speed while maintaining manageable device complexity through modular architecture.
2Device complexity
If a single control module is used to control the entire array antenna module, then the wiring structure is simplified, but the transmission speed deteriorates due to the huge amount of data
Solution Approach 1:
The wiring structure is segmented into multiple independent control zones, where each control module manages its own beamforming modules and associated wiring. This reduces the data transmission burden on any single wiring path while enabling parallel data flow across multiple wiring channels, thereby improving overall transmission speed.
3Adaptability or versatility
If the array antenna module is made large to accommodate more antennas, then the coverage and communication capability are improved, but the area occupied increases and wiring becomes more difficult
Solution Approach 1:
The array antenna module is divided into multiple smaller beamforming module zones, each independently controlled. This segmentation allows the system to achieve large-scale coverage capability through modular expansion rather than requiring a single large monolithic structure, reducing wiring complexity and improving manageability while maintaining enhanced coverage and communication capability.
