Electromagnetic Compatibility and Radio Spectrum Matters (ERM); Radio Equipment to Be Used in the 24 GHz Band; System Reference Document for Short Range Radar
|Publication Date:||1 July 2001|
The present document applies to Short Range Devices (SRD) in the field of SRR operating at very low power levels for exterior automotive applications for vehicle environmental sensing.
These applications require antenna characteristics, which necessitates only narrow elevation antenna beam combined with a limited mounting height.
The document describes the technical characteristics of SRR's, the Radio frequency requirements as a wideband emission mask, for the carrier frequency operating in the 24 GHz SRD as specified in CEPT/ERC Recommendation 70-03 . The devices also use the SRD Band for a movement sensor function implementing a Doppler mode for a target speed measurement function.
The EN 301 091  presents a basis for the new cost efficient and versatile 24 GHz radar technology, which complements 77 GHz Automotive Cruise Control (ACC) functions.
The following information is given in:
• Annex A: Detailed market information;
• Annex B: Technical information;
• Annex C: Expected compatibility issues.
