Solution Overview

Problem

Conventional imaging systems on mobile carriers, such as aircraft, consist of separate radiofrequency and optronic systems with different capture ranges and angles, requiring complex data registration to merge image data, which can lead to errors in fusion.

Innovation Solution

An integrated multi-sensor support panel with a radiating surface containing both radiofrequency and optical sensors, allowing for co-located capture fields without the need for data registration, utilizing a planar antenna structure with optical sensors positioned to preserve the antenna pattern and provide digital image data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate radiofrequency and optronic systems are used, then each system can operate independently with its own capture range and angles, but complex data registration is required to merge image data which can lead to errors in fusion

Engineering Contradiction:
Improvedata fusion accuracyVSAvoiddata registration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines radiofrequency sensors and optical sensors into a single integrated multi-sensor support panel with a common radiating surface. This merging eliminates the need for complex data registration between separate systems, as all sensors share the same physical location and capture fields, thereby improving data fusion accuracy while reducing registration complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated support panel serves multiple functions simultaneously: it acts as both a radiofrequency antenna array and a mounting structure for optical sensors. This multi-functionality allows different sensor types to operate from a single platform with co-located capture fields, resolving the contradiction between system independence and data fusion simplicity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If optical sensors are positioned on the radiating surface, then co-located capture fields are achieved without registration, but the antenna pattern may be disturbed

Engineering Contradiction:
Improvecapture field alignmentVSAvoidantenna pattern stability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent applies local quality by strategically positioning optical sensors at specific locations on the radiating surface where they do not interfere with the antenna pattern. The support panel structure provides localized mounting positions that maintain both capture field alignment and antenna performance, allowing optical sensors to be integrated without disturbing the overall antenna radiation characteristics.

Inventive Principle:
Principle #3Local quality

3Productivity

If multiple sensor types are integrated on the same panel, then data exploitation efficiency is improved without registration, but the device complexity increases

Engineering Contradiction:
Improvedata exploitation efficiencyVSAvoidsensor integration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The multi-sensor support panel is designed as a universal platform that accommodates both radiofrequency and optical sensors simultaneously. This unified structure improves data exploitation efficiency by providing co-located capture fields that eliminate registration requirements, while the standardized panel design actually reduces overall system complexity compared to managing multiple separate sensor platforms.

Inventive Principle:
Principle #6Universality (Multi-functionality)
