Abstract
Although radar is an important component of aircraft surveillance systems used in air traffic control, its
performance parameters such as data refresh rate, which depends on antenna rotation period or position
estimation accuracy, do not satisfy the requirements for high density operation. Multilateration utilizing
hyperbolic positioning is a newly proposed surveillance system that is said to have better performance
than conventional radar systems. We applied Radio over Fiber to a multilateration system and achieved
improved performances. We confirmed our evaluation results in an actual airport environment.
