Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizen Windelight for the clue delivery! CTOnews.com March 31 news, the Ministry of Industry and Information Technology recently issued the "Notice on Printing and Distributing the Interim Provisions on Radio Management of Foreign Object Detection Equipment on Civil Airstrips"(hereinafter referred to as the "Notice"), clarifying the 92-94GHz frequency band as the main frequency of airport runway foreign object (FOD) detection equipment.

In addition, the 76-77GHz band will be used as a supplementary frequency, and the radio frequency license for the above frequency band will be implemented in a hierarchical management mode, and the RF technical requirements for FOD detection equipment and the interference avoidance requirements between FOD detection equipment and automotive radar in the 76-77GHz band will be established.

CTOnews.com learned from the official website of the Ministry of Industry and Information Technology that in order to solve the radio interference problem between FOD detection equipment and other radio services, relevant departments also put forward the following requirements:

In order to realize the compatible coexistence of 76-77GHz frequency band FOD detection equipment and automobile radar frequency, it is necessary to set up electromagnetic environment protection zone on the periphery of airport runway when airport setting is clarified and FOD detection equipment is used.

Second, in order to avoid harmful radio interference between multiple sets of FOD detection equipment at the same airport, airport management agencies are required to take measures such as frequency division and spatial isolation.

Third, in order to improve the anti-interference ability of FOD detection equipment itself, it is required to adopt redundant detection, background cancellation, data correlation and other technologies.

The promulgation of the Regulations will effectively improve the frequency compatibility and sharing level between relevant radio systems, reduce interference risks, give full play to the leading and driving role of spectrum resources in the radio industry, and improve the informatization level of industry safety supervision.
