Problem
Existing electromagnetic wave detection systems face challenges in accurately aligning the actual emission direction of electromagnetic waves with the estimated emission direction, leading to misalignment and inefficiencies in detection processes.
Innovation Solution
An electromagnetic wave detection apparatus and system that includes an irradiator, a detector, a propagation unit with multiple pixels that switch between propagating and non-propagating states, and a controller that updates the emission direction information based on the position of the propagation elements, ensuring accurate alignment and reducing misalignment between the actual and estimated emission directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the emission direction information is not updated based on propagation element position, then the system structure remains simple, but the alignment accuracy between actual and estimated emission directions deteriorates
Solution Approach 1:
The controller updates the emission direction information stored in memory based on feedback from the actual position of propagation elements. This closed-loop feedback mechanism ensures that the emission direction information accurately reflects the current spatial configuration of propagation elements, thereby maintaining high alignment accuracy without requiring complex mechanical alignment structures
Solution Approach 2:
The system automatically updates its own emission direction information using data from its own propagation elements. The controller reads position information from memory and uses it to update emission direction parameters without external intervention, enabling the system to self-correct and maintain accuracy while keeping the overall structure relatively simple
2Adaptability or versatility
If multiple propagation elements are used to switch reflected waves, then the detection coverage is improved, but the coordination complexity between elements increases
Solution Approach 1:
The propagation unit is divided into multiple independent propagation elements (e.g., pixels or sub-apertures) that can be independently controlled. Each element can switch between propagating and blocking reflected waves, allowing the system to cover different spatial regions and adjust detection coverage by activating specific segments without coordinating complex movements across all elements
Solution Approach 2:
Multiple propagation elements perform the same basic function (switching reflected waves) but can be independently configured for different purposes. This allows the system to achieve multiple detection goals simultaneously using identical component types, reducing the need for specialized coordination mechanisms while expanding detection coverage
3Measurement precision
If the emission direction information is frequently updated, then the alignment accuracy is improved, but the processing time and energy consumption increase
Solution Approach 1:
The controller updates emission direction information at periodic intervals or at specific trigger events (e.g., when propagation element positions change) rather than continuously. This periodic update approach maintains sufficient alignment accuracy for most applications while significantly reducing processing time and energy consumption compared to continuous updates
Solution Approach 2:
The system changes the update frequency parameter of emission direction information based on operational conditions. During critical measurement phases, updates occur more frequently to maintain high accuracy, while during stable or non-critical phases, update frequency is reduced to minimize processing overhead and energy consumption

AI summary
An electromagnetic wave detection apparatus (10) includes an irradiator (11), a first detector (17), a propagation unit (20), a memory (13), and a controller (14). The irradiator (11) irradiates electromagnetic waves. The first detector (17) detects reflected waves of the electromagnetic waves irradiated onto an object (ob). The propagation unit (20) includes propagation elements (px). By irradiation position of the electromagnetic waves irradiated onto the object (ob), the propagation elements (px) switch between propagating and not propagating the reflected waves towards the first detector (17). The memory (13) stores information related to the emission direction of the electromagnetic waves. The controller (14) updates the information related to the emission direction based on the position of the propagation element (px) that is propagating the reflected waves toward the first detector (17) when the first detector (17) detects the reflected waves.
