Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-sized measurement systems, distortion in non-metallic measurement mechanisms interferes with the accurate measurement of communication performance due to the interference of distortion detectors using laser light with the radio waves being measured.
Innovation Solution
A measurement apparatus that includes a hardware processor connected to a memory, functioning as a first acquisition unit, calculation unit, and correction unit, which acquires and corrects radio wave phases to account for distortion in the support members, allowing for precise communication performance measurement by calculating ideal and actual radio wave phases and applying corrections based on distortion information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a distortion detector using laser light is applied to detect distortion in the measurement mechanism, then the distortion detection capability is improved, but the detector becomes a reflection object of the radio wave to be measured and interferes with the measurement
Solution Approach 1:
The patent extracts the harmful function of the distortion detector by removing the laser light source and detector from the measurement system. Instead of using optical detection, the system relies on radio wave phase measurements to detect support member distortion, thereby eliminating the interference problem while maintaining distortion detection capability
Solution Approach 2:
The patent replaces the optical detection system (laser-based distortion detector) with a radio wave-based detection system. By using phase difference measurements of radio waves received by the antenna, the system achieves distortion detection without the harmful side effects of laser-based optical detection
2Area of stationary object
If a large-sized measurement system is introduced to receive radio waves from a large-sized measurement target, then the measurement coverage is improved, but distortion occurs in the non-metallic measurement mechanism
Solution Approach 1:
The patent implements a feedback mechanism where the phase difference of received radio waves is continuously measured and used to calculate support member distortion. This distortion information is then fed back to correct the communication performance measurement results, enabling the large-sized system to compensate for its own structural distortions and maintain measurement accuracy
Solution Approach 2:
The patent changes the measurement parameter from direct physical position measurement to radio wave phase measurement. By measuring the phase of radio waves at different frequencies and positions, the system can detect support member distortion and compensate for it, allowing large-sized non-metallic structures to be used without compromising measurement stability

AI summary
A measurement apparatus outputs a correction result obtained by performing correction on a target radio wave received by a measurement mechanism which includes an antenna for receiving the target radio wave and a support member for supporting the antenna. The measurement apparatus acquires a first received radio wave phase being a phase of the target radio wave received by the antenna from a target. The measurement apparatus calculates an ideal phase of the target radio wave at each position of the antenna. The measurement apparatus acquires a second received radio wave phase being a phase of the target radio wave received by the antenna from the target at each position of the antenna. The measurement apparatus performs correction based on distortion of the support member, which is calculated from a difference between the ideal phase and the second received radio wave phase.
