To ensure the fidelity of the ILS signal, the errors must be strictly controlled. The benchmark calibration flight precision control had very few attentions as the criterion. Therefore, through the computer to build a relatively complete set of airport simulation environment, we can design a control system and intuitive way to monitor the signal used to get rid of a variety of factors lead to errors. This showed the calibration results were unstable. The insightful significance is that this provides a guideline for the visualization and conformity of complex electromagnetic environment.
With the low-altitude airspace opening, the role of surveillance technology in ATC system has increasing prominent. This article used application of image extraction technology, algorithm processing, data fusion and transmission to improve the reliability of surveillance and set up a new structure of network. Finally, we used computers to achieve a new type of low-altitude surveillance system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
