The Rydberg atomic communication antenna exhibits exceptional properties superior to traditional antennas. use of heterodyne technology further establishes a foundation for high-precision digital communication. However, current signal solvers limit its application in integrated radar-communication systems. To address this, we propose multi-parameter mapping model between symbols and the receiver signals under radar interference. Based on this model, introduce an adaptive...
Humidity sensors are widely used in various fields of life. In meteorological detection, the sensor must have high sensitivity and fast dynamic response time due to extreme environmental interference. However, sensitive mechanism humidity determines that will inevitably be increased while improving sensitivity, which undoubtedly creates difficulties for design. This article takes interdigitated capacitive as research object proposes an optimal design scheme considers sensitivity. By...
To meet the needs of a large number high-altitude meteorological detections, we need to perform fast, high-precision, and high-reliability calibrations sensors in atmospheric detection system (ADS). However, using traditional method calibrate sensor with high precision often takes lot time increases cost workforce material resources. Therefore, for realizing fast calibration under current hardware conditions is required. A physical field model Tube–Air–ADS proposed first time, transfer...
Abstract This paper aims to enhance the efficiency of sensor structural optimization design and achieve rapid performance evaluation automatic layout drawing. To this end, we propose a parameterized model resonant differential MEMS pressure (PRDMP). It can complete sensitivity calculations within 1 ms, far faster than traditional finite element analysis (FEA) methods. Additionally, compared FEA results, its accuracy exceeds 90%. Furthermore, reconstructed uncertainty part PRDMP based on an...
Humidity sensors have been widely used in various fields of life, among which sensitivity is one the most important indicators for its evaluation. Quantitatively analyzing effect structural errors on a big challenge sensor design. To address this problem, paper proposes uncertainty analysis method. By establishing mathematical model and propagation model, influence interdigital capacitive humidity sensor's quantitatively analyzed. The accuracy superiority proposed method are also verified by...
Bridges with concrete structures are prone to phenomena such as cracking, which poses a significant threat railway operational safety. Currently, unmanned aerial vehicles (UAV) has been employed for bridge health monitoring. However, the existing UAV payloads not specifically designed inspection and encounter several issues during operation. In light of this, this paper proposes low-power, omni-directional vision payload inspection. The is equipped four cameras, laser rangefinder,...
