The IARU Monitoring System is a worldwide service authorized by the IARU Administrative Council. It is served by many dedicated volunteers. You can read about the History of the IARU Monitoring System R1 here.
The primary objective of the IARU Monitoring System is the search, classification, identification and initiation of steps leading to the removal from amateur bands of radio signals of non-amateur stations causing harmful interference to the amateur services, contrary to ITU International Telecommunications Union and national radio regulations. Typical intruders include Broadcasters, Over the Horizon Radars, illegal operators on the bands including taxicabs and fishermen on various bands, various military modes and many more types of unwanted signals.
Interested parties who want to report intruders on the amateur bands are encouraged to send their observations to the Regional Coordinator including the following information: your identification (organization-callsign), the frequency, time in UTC, day, month, any possible identification of the signal, mode, signal strength and any remarks that help describe the signal, may be also a radio location. In addition, a very beneficial piece of information is an Audio recording of the signal preferably as a .wav file.
Reports of intruders in the amateur bands can be submitted via the IARUMS R1 Intruder Logger

The role of the IARU Monitoring System (IARUMS) — monitoring the amateur bands to search and identify transmissions sent by intruders — is important because the amount of all kind of intruders is rapidly growing!
A number of national Monitoring Coordinators and volunteers have been watching our bands for many years. But more needs to be done to raise awareness of societies and countries where there no national monitoring team exists . Also, existing groups can still help by sharing detailed information worldwide with others. Monitoring is Teamwork!
