Continental ARS 548 4D Imaging Millimeter Wave Radar

1. Produk Langkungview

The Continental ARS 548 RDI is a high-precision 4D imaging millimeter wave radar sensor designed for advanced driver-assistance systems (ADAS) and autonomous driving applications. It operates at 77 GHz and provides long-range detection capabilities up to 300 meters, offering stereoscopic perception for enhanced environmental understanding.

This rugged sensor independently measures distance, speed (Doppler principle), and angle of objects without reflectors. It utilizes a pulsed compression and New Frequency Modulation (NFM) measurement procedure. The improved range resolution is available in the complete Field of View (FoV) with a real-time scanning frequency of 20 times per second. Simultaneous detection output of target distances up to 300 meters, relative speed, and angle for each target in azimuth and elevation is provided with RDI (Radar Detection Interface).

Aplikasi konci:

• Anti-collision protection for autonomous vehicles.
• Headway control for near and far range.
• Area monitoring for hazardous or restricted zones.
• Classification of objects, including height measurement.
• Object detection in crowded or unclear environments.

Advantages:

• Fast and Safe: Excellent measuring performance and high operational safety.
• Bisa dipercaya: Fail-safe operation under all circumstances.
• Robust and New Design: Utilizes the newest radar technology for mass production in automotive supply industry.

2. Setup jeung Instalasi

Proper installation is crucial for the optimal performance of the ARS 548 RDI radar. Due to the complexity and safety-critical nature of its application, professional installation is highly recommended.

komponén:

• Continental ARS 548 RDI Radar Unit
• Wiring Harness (specific to application)
• DB9 Connector (for data interface, e.g., CAN)

Titik Sambungan:

The radar unit features two multi-pin connectors on its rear for power, data, and control signals. Ensure all connections are secure and correctly oriented to prevent damage.

Pamasangan:

The radar should be mounted securely in a location that provides an unobstructed view of the area to be monitored. Refer to the vehicle or system-specific integration guidelines for optimal placement and calibration. The housing is designed for robust outdoor use.

3. Prinsip Operasi

The ARS 548 RDI operates by emitting millimeter waves and analyzing the reflected signals to detect objects, measure their distance, speed, and angular position (azimuth and elevation). The 4D imaging capability provides a rich point cloud representation of the environment.

Kaluaran Data:

The sensor provides real-time data on detected objects, including their ID, X and Y coordinates, height, speed, and Radar Cross Section (RCS). This information is typically transmitted via a BroadR-Reach Ethernet interface.

Range and Azimuth Performance:

The radar's detection range varies based on the object type and its Radar Cross Section (RCS). The graph below illustrates typical range performance across different azimuth angles for various targets.

4. Pangropéa

The Continental ARS 548 RDI is designed for robust and maintenance-free operation under normal conditions. However, periodic checks can help ensure its longevity and performance.

• beberesih: Keep the front surface (radome) of the radar unit clean from dirt, ice, snow, or other obstructions that could interfere with radar signal transmission and reception. Use a soft cloth and mild cleaning solution if necessary.
• Inspeksi Fisik: Periodically inspect the unit for any signs of physical damage, loose connections, or corrosion on the connectors.
• Apdet parangkat lunak: Ensure the radar's firmware and associated control software are kept up-to-date as recommended by Continental or the system integrator.
• Perlindungan Lingkungan: While the unit has an IP6K9K rating, avoid exposing it to extreme mechanical stress or harsh chemicals.

5. Cara ngungkulan

If you encounter issues with your Continental ARS 548 RDI radar, consider the following basic troubleshooting steps:

• No Detection/Intermittent Detection:
  • Check for any obstructions in front of the radar unit (dirt, ice, foreign objects).
  • Verify all power and data connections are secure and correctly seated.
  • Ensure the radar unit is receiving adequate power within the specified voltage rentang.
  • Confirm that the radar's field of view is not blocked by vehicle components or external structures.
• Kasalahan Komunikasi:
  • Check the integrity of the Ethernet (BroadR-Reach) cable and connectors.
  • Verify the communication settings (e.g., IP address, port) in the host system's software.
  • Ensure the host system's network interface is functioning correctly.
• Gangguan sistem:
  • Perform a power cycle of the radar unit and the connected system.
  • Consult the diagnostic tools or logs provided by your system integrator for specific error codes.

For persistent issues, contact your system integrator or Continental technical support.
