High-accuracy radio wave-based automatic measurement

Automatic high-accuracy measurement through unique radio measurement technology

RD-90 Aircraft Approach Detection and Identification Device

Focusing on the specific radio waves emitted by aircraft, the RD-90 automatically measures aircraft noise with high accuracy by comparing the strength of the radio waves and the noise level (radio wave identification method). This technology makes automatic extraction of aircraft noise possible from among automatically measured data containing various measured noises other than aircraft. The ability to understand the flight configuration for each aircraft by aggregating the data processing abilities of automatic measuring instruments in multiple locations allows for more accurate automation.

Various merits offered by radio wave identification method

? Identify aircraft with no influences from weather conditions and surrounding environments.
? Analyze the received radio waves to verify altitude changes of aircraft.
? Obtain individual identification information of aircraft using radio wave analysis.
