Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional night vision technologies are ineffective in fog, smoke, or precipitation and provide limited peripheral vision, posing hazards in low-light conditions, and existing handheld radar systems are not integrated with goggles and offer limited coverage.
Innovation Solution
A personal area radar system mounted on a helmet with multiple radar antennas and a processor to transmit and receive radar signals, providing a 360-degree field of view and displaying object locations, capable of penetrating through solid objects and weather conditions, using advanced semiconductor technology for a lightweight and power-efficient phased array radar system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional night vision technology is used, then the user can see in low-light conditions, but the technology provides little to no benefit in fog, smoke or precipitation and has limited field of view
Solution Approach 1:
The patent combines radar technology with night vision goggles to create an integrated system. The radar component detects objects by emitting electromagnetic waves and analyzing reflections, providing detection capability in conditions where optical night vision fails (fog, smoke, precipitation). The system merges radar-derived spatial information with the night vision display, allowing the user to see through multiple environmental obstacles simultaneously.
2Ease of manufacture
If conventional handheld radar systems are used, then the system can penetrate walls to scan for items, but the system requires a separate dedicated radar not integrated with the goggle display and has limited peripheral coverage
Solution Approach 1:
The patent integrates radar transmitting and receiving components directly into the night vision goggle structure. The radar antenna is incorporated into the goggle housing, and the radar signal processing is merged with the goggle's existing image processing pipeline. This unified design eliminates the need for separate handheld radar devices and provides seamless integration between detection and display functions.
Solution Approach 2:
The integrated radar-goggle system performs multiple functions: it detects objects in all directions (360-degree coverage), penetrates walls to scan for hidden items, provides real-time spatial awareness, and displays information through the existing goggle interface. This multi-functional system replaces the need for multiple separate devices (handheld radar, night vision goggles, peripheral sensors).
3Adaptability or versatility
If a 360-degree field of view radar system is implemented, then the user achieves full situational awareness, but the system requires multiple radar antennas and increased processing capability
Solution Approach 1:
The patent divides the radar detection task across multiple antenna elements distributed around the goggle structure. Each antenna segment covers a specific angular sector, and the system processes reflections from each segment separately. This segmented approach enables 360-degree coverage while allowing independent optimization of each antenna element and simplifying the processing load for each detection zone.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances situational awareness by providing a full 360-degree view of surroundings through fog, smoke, and darkness, enabling detection of objects behind solid objects and hazards, with friend-or-foe identification and low power consumption, suitable for military and emergency personnel.
Implementation Method 1
one or more radar antennas on the helmet configured to transmit a radar signal and receive the radar signal when returned from reflection off an object
Implementation Method 2
receive the radar signal when returned from reflection off an object

AI summary
A personal area radar is provided to permit a user to be aware of their surroundings. This may be in 360 degrees or any other suitable coverage area and angle. The personal area radar can show objects to the user through fog, smoke, precipitation, darkness and with full 360 degree field of view capability, significantly improving the user's overall situational awareness. They may also be used to view things that are behind solid objects such as in or behind walls or underground. These systems may be highly integrated phased array radar systems mounted on a helmet. They may use small, high frequency radars able to detect solid objects (and/or semi-solid objects) such as people, improvised explosive devices (IED), or other solid objects. These methods and systems may provide the user with 360 degrees view and awareness of objects regardless of external conditions such as weather, darkness or other obstructions.
