ICAO POLICY No change to the radionavigation allocations in Region 2 and Region 3. AVIATION USE: These bands supplement the 15.4–15.7 GHz band for airport surface detection equipment (ASDE). The higher frequency provides greater target resolution although performance in precipitation, such as rain and fog, is inferior. Footnote 5.533 should be noted. In 1997 the need to retain this allocation was reconfirmed. The ASDE requirement COMMENTARY: assumes greater priority with increasing airport congestion.
