EN 303 345 2 Short Range Automotive Radar Wireless Test
The EN 303 345 series of standards is designed to ensure the interoperability and safety of short range automotive radar systems. This particular test, defined in EN 303 345-2, focuses on evaluating the performance and compliance of short-range automotive radars with respect to emissions levels as per European regulations.
The test involves a series of rigorous checks that ensure the radar devices do not emit harmful electromagnetic interference (EMI) that could disrupt other electronic systems within vehicles or nearby infrastructure. This is crucial for maintaining the reliability and safety of connected vehicle technologies, which are becoming increasingly integral to modern automotive design.
During this test, a calibrated measurement device is used to monitor the emissions from the radar system under various operating conditions. The testing environment typically includes controlled parameters such as frequency bands, modulation types, and power levels to simulate real-world driving scenarios. Compliance with these standards ensures that automotive radars can operate safely alongside other wireless devices without causing interference.
The test setup is designed to mimic the operational environment of a vehicle in motion, which involves complex interactions between multiple systems including communication protocols, hardware configurations, and software settings. This comprehensive approach guarantees that any radar system meeting this standard will perform reliably under all expected conditions.
- Ensures Interoperability: Compliance with EN 303 345-2 ensures seamless integration of short-range automotive radars into broader vehicular networks, enhancing overall system efficiency and reliability.
- Increased Safety: By eliminating harmful emissions, this test contributes significantly to the safety of both passengers and pedestrians by reducing risks associated with EMI interference.
