Enhancing Millimeter Wave Radar Testing with Sunyield’s SY-CATR Series

In the realm of millimeter wave detection, precision and efficiency are paramount. Sunyield, a pioneer in cutting-edge measurement systems, introduces the SY-CATR series, compact range antenna measurement systems designed to elevate millimeter wave radar testing. These systems offer an exceptional experimental environment for millimeter-wave radar testing and design across various applications. Let’s delve into the features and benefits of Sunyield’s SY-CATR series.

Wide Frequency Band and Small Size

The SY-CATR series stands out for its ability to accommodate the wide frequency band and compact size of millimeter wave radar technology. Whether you’re testing automotive radars, military/police radar products, or civilian millimeter wave antennas, these systems provide an ideal platform for your experiments.

Innovative Integral Curling Surface

Sunyield’s SY-CATR series incorporates an integral curling surface with a remarkable root mean square (RMS) deviation of less than 20 micrometers. This innovation not only saves space but also enhances measurement accuracy when compared to conventional saw-tooth reflectors.

Versatile Active and Passive Testing

These systems are designed for versatility. Their bias feed design makes them suitable for both active and passive testing. Whether you’re conducting tests with a network analyzer or a spectrum analyzer, the SY-CATR series can create an elliptical quiet zone within a specified longitudinal distance to meet your testing needs.

Customization and Convenience

To cater to diverse user requirements, Sunyield equips the SY-CATR series with a multi-dimensional bearing turntable, allowing customization of test tooling and electric auxiliary shafts. This flexibility ensures that the systems adapt seamlessly to your unique testing setups.

Sunyield understands the importance of ease of use. Each SY-CATR system comes with a fully shielded non-reflective microwave chamber, complete with an adjustable feed fixture and the corresponding band ripple speaker feed. Additionally, the movable base simplifies placement and deployment, ensuring a hassle-free testing experience.


In the realm of compact range antenna measurement, Sunyield’s SY-CATR series sets a new standard for precision, versatility, and convenience. Whether you’re in the automotive, military, or civilian sector, these systems empower you to conduct millimeter wave radar testing with unparalleled accuracy and efficiency. Elevate your testing capabilities with Sunyield and revolutionize your millimeter wave radar design and development processes.
