Method To Generate High Precision Trajectory Based On Multi-souce Information Fusion And Application

Measuring to control a data processing is smoothly progress the core contentswhich promises that the aerospace experiments. The data processing undertakesaerospace mission to shoot gloriole to learn a picture, telemetering, outside measure,target characteristic etc. the comprehensive processing of the data, data processing as aresult decide to fly experiment the on trial analyzing result of mission and shootconclusion; Still experiment for each kind of flight of solid hour monitor, fall point toforecast and for safe control system in the ground provide solid hour measure aninformation.How well make use of optics, radar, telemetering, GPS etc. various different typesmeasure an on the trail of diagraph data of control the equipments and aim at a highdynamic state target a research solid hour, quasi-solid hour and the after the event datablend treatment, acquire accurate and dependable of experiment information, raise theestimate accuracy of ballistic parameter, to aerospace aircraft design, improve meaningof have the importance.The textual and main research work have studied many source information fusion amethod, include the fusion method of the after the event data sum solid hour, quasi-solid hour the data blend a method; Two, studied a non-linear filtering method, includemobile target sport model, expand a Kalman filtering method, according to without theKalman filtering method of trace, spur transformation, hybrid Kalman filtering method,and imitate of each kind of filtering method true application;Three, comprehensiveabove of many source information fusion method and non-linear filtering method,andcarried on a research result to imitate a true application.This text multiple point solves not to wait the on the trail of data of accuracyequipments and incompletely measures the processing problem of the fusion of data, themethod for provide from measure a dollar data to prepare to handle many the sourcedata blend a model establishment,and solve to high accuracy trajectory of theengineering dissolve calculate method, valid exaltation measure utilization and theoutside ballistic parameter of control the equipments of solution calculate accuracy.
