Aircraft passage analysis

Patented technology for determining the time of closest approach

The radio waves emitted by aircraft make it possible not only to check the altitude of the aircraft but also to understand the status of the aircraft's passage. This allows for automatic calculation of the time at which the aircraft will be closest to the noise measurement location, thus improving automatic measurement accuracy. This patented technology (industrial property right: measurement method for aircraft point-blank passing time, etc.) is included as a standard function in all Nihon Onkyo Engineering aircraft noise measuring instruments currently on sale.

More detailed understanding of aircraft passage

Thanks to added functionality utilizing more sophisticated sensors, not only can the time of closest approach for an aircraft be determined, but the aircraft's passing position and flight direction can also be obtained.
