Research on High-pressure Water Jet Target Object Detection Parameter Optimization

摘要

By using the unique characteristics of high pressure water jet,sound test,analysis and recognition techniques combined with high pressure water jet,collecting target reflected sound signal characteristic value,then by the analysis processing,to achieve recognition for classification purposes,can form a kind of brand-new landmine detection method.For the ultimate realization of the target of effective detection and classification,it must be determined on the reflected sound signal of water jet hydraulic parameters and reasonable choice of the walking device and a signal acquisition device parameters.Effects on reflected sound signal characteristic value quality parameters include:nozzle diameter,jet pressure,nozzle and the target of target distance,jet angle and jet scanning speed.By parameter optimization,the system can complete identification of material and geometry of eigenvalue.
