1. Purpose and Legal Basis
This Regulation is formulated in accordance with laws, regulations and normative documents including the Regulations on Radio Administration of the People's Republic of China and the Radio Frequency Allocation Regulations of the People's Republic of China, and with reference to the relevant requirements of the ITU Radio Regulations, so as to implement the national new-type industrialization development strategy, effectively guide and regulate the sound and orderly development of the radar industry, and promote the efficient use of radio spectrum resources.
2. Definitions
The term "radar" in this regulation refers to a radio determination system located within the Earth’s atmosphere that compares the characteristics of a reference radio signal with signals reflected or retransmitted by a target object to determine parameters such as the target’s position, velocity, and direction of movement, or to obtain information related to these parameters (including airborne radar and unmanned aerial platform radar).
3. Radio Frequency and Station Management

2、Roadside traffic radar: 92—94GHz
Disaster Prevention and Mitigation Radar (Hydrological, Geological, Marine, etc.)
1、Marine radar: 4438—4488kHz, 5250—5275kHz, 9305—9355kHz, 13450—13550kHz, 16100—16200kHz, 24450—24600kHz, 26200—26350kHz, and 39.5—40MHz
2、Hydrological radar: 402—403MHz, 9100—9500MHz
3、Ground-based deformation monitoring radar: 15.7—17.2GHz
Micro-Target Detection Radar
1、Micro-target detection radar (including insect, bird, and drone detection radar): 2900—3100MHz, 9000—10000MHz, and 15.7—17.2GHz
Other Radar
1、Short-range detection radar and unmanned aerial vehicle radar use the 24—24.25GHz band, with requirements per MIIT Announcement No. 52 of 2019.
(2) Licensing Management
1、Frequency use licenses for radar covering three or more provinces shall be issued by the national radio administration authority.
2、Frequency use licenses for radar covering two provinces or within one province shall be issued by local radio administration authorities.
3、To streamline approval, reduce user burden, and improve efficiency, provincial radio authorities may integrate station licensing and frequency licensing processes.
4. Equipment Management
(1) Type Approval
Radar radio transmission and reception equipment must comply with the RF technical requirements in Annex 2 of this regulation. Manufacturers, importers, or developers of radar equipment for domestic sale or use must apply to the national radio administration authority for type approval.
(2) Electromagnetic Radiation Protection
Radar users must comply with national environmental protection regulations and take necessary measures to prevent electromagnetic radiation pollution.
5. Radar Interference Coordination
(1) Coordination Principles
In case of harmful interference, users may complain to local radio authorities, who will coordinate based on the principles of "out-of-band yielding to in-band, secondary services yielding to primary services, later users yielding to earlier users, and unplanned yielding to planned."
(2) Special Protection
Special protection is granted to frequencies for aviation radio navigation, maritime radio navigation, satellite radio navigation, and ITU Appendix 15 "Global Maritime Distress and Safety System" frequencies.
(3) International Coordination
Radar deployment in border areas must comply with bilateral frequency coordination agreements and international rules.

6. Transition Policies and Effective Date
- After January 1, 2026, the national radio authority will no longer accept or approve type approval applications for radar equipment inconsistent with this regulation.
- Existing type approvals will not be renewed upon expiration.
- All levels of radio management authorities will no longer accept new applications for radar frequency usage permits or applications for the establishment and use of radio stations (stations). These applications are inconsistent with the provisions of this regulation.
- Radar radio stations (stations) that have been legally established and put into use can continue to be used after the expiration of the radio frequency usage period or the validity period of the radio station license. They can still submit applications to the radio management authority for the continuation of the use of radio frequencies and radio stations (stations) until the original equipment is scrapped.
