The ITU Radiocommunication Assembly, considering that radar systems can produce interference to digital radio-relay systems (DRRSs) in some situations; that there are two coupling mechanisms by which radiated energy from radar stations may be coupled into radio-relay systems: radar spurious emission in the radio-relay bands; radio-relay system front-end overload (receiver desensitization) caused by the radar fundamental frequency; that the most desirable method of mitigating the interference may be to reduce the spurious emissions at the radar transmitter to a sufficiently low level; that some of the techniques employed by radio-relay system designers to enhance system performance are expected to reduce the susceptibility of these systems to interference from radar transmitters.

This Report presents an overview of Inspections Procedures in response to Question ITU-R 225/1 regarding inspection techniques and procedures. The Question relates to how administrations proceed in planning and conducting radio station inspections. The purpose of this Report is to provide general guidelines for planning and performing inspection activities on various types of radio stations. Inspection activities often include review and verification of both technical and administrative conditions assigned to a radio station or other spectrum user. Although the term “licensed” is used throughout the document, this term can be considered here to include not only stations with licences issued by the regulatory authority, but also other authorized spectrum users (such as those operating with “licence exempt” devices like low-power radios and RF devices operating under equipment standards approval). The primary focus of this report is to consider inspections that are conducted “on-site”, by visiting the transmitter location. Included in Annexes are some specific examples in certain services, toprovide examples of howthe general guidelines can be applied. This Report should be considered a general guidance document for inspections planning.
