风险对冲策略复原传感数据的可行性分析

Feasibility Analysis of Sensor Data Recovery by Risk Hedging Strategy

传感装置运动轨迹偏离预期路径,可能导致传感数据特征发生混乱,影响检测效果。以某声波-弹性波耦合模型为例,在其传感装置布置和传感系统偏离性态的基础上进行风险分析,研讨传感系统连同传感装置发生偏离对传感数据特征的影响,根据传感装置中各发射器/接收器的潜在贡献提出风险对冲策略,评估其对传感数据的最大复原程度。分析表明,鉴于传感系统偏离对各方位的传感数据具有一定的对等补偿作用,风险对冲策略可以成为传感数据复原的有效解决方案。

The motion trajectory of the sensing device deviates from the expected path, which may cause confusion in the characteristics of the sensing data and affect the detection effect. Taking an acoustic wave-elastic wave coupling model as an example, the risk analysis is carried out on the basis of the arrangement of the sensing device and the deviation behavior of the sensing system, and the influence of the deviation of the sensing system and the sensing device on the characteristics of the sensing data is discussed. The potential contribution of each transmitter/receiver in a sensing device proposes a risk hedging strategy that evaluates its maximum recovery to the sensing data. The analysis shows that since the deviation of the sensing system has a certain reciprocal compensation effect on the sensing data in all directions, the risk hedging strategy can be an effective solution for the restoration of the sensing data.
