P roduct Brochure | Version 01.00 R&S®QAR Quality Automotive Radome Tester A new era in material characterization
Open the catalog to page 1R&S®QAR Quality Automotive Radome Tester At a glance The R&S®QAR is a millimeterwave imaging system for the most demanding radome material and fascia measurements and validations. Thanks to its outstanding performance, speed, quality and intuitive operation, it is the perfect tool for applications ranging from development and production to verification of radome material and integration of 76 GHz to 81 GHz radars. Operating in the 72 GHz to 82 GHz frequency range, the R&S®QAR is ideal for verifying materials that will cover a radar sensor. With its support of spatially resolved reflection...
Open the catalog to page 3R&S®QAR Quality Automotive Radome Tester Benefits and key features For all your needs The R&S®QAR heralds a new era in material characterization. When developing and verifying any type of 77 GHz/79 GHz radome material, the R&S®QAR always sees what your radar will see – but with super high resolution. ▷▷ page 5 Active array technology Hundreds of electronically controlled transmit and receive antennas make the R&S®QAR a fast, reliable and high- performance millimeterwave imaging system. ▷▷ page 6 Spatially resolved reflectivity measurements The R&S®QAR measures the spatially resolved...
Open the catalog to page 4For all your needs Advanced RF measuring equipment must, above all, be flexible. Performance and functionality requirements vary depending on the test setup and application. The R&S®QAR heralds a new era in material characterization. When developing and verifying any type of 77 GHz/79 GHz radome material, the R&S®QAR always sees what your radar will see – but with super high resolution. Versatile configuration Thanks to its modular design, the R&S®QAR can be equipped with a main module and transmitter module (option) to meet the requirements for a specific task. The main module performs the...
Open the catalog to page 5Active array technology The system’s active components are the main module and the optional transmitter module. The main module consists of carefully distributed transmit and receive antenna rrays a that enable the main module to create millimeterwave images of devices under test (DUT) as large as 30 cm × 50 cm. The technology used in the R&S®QAR does not rely on moving parts, but on hundreds of electronically controlled transmit and receive antennas. This makes the R&S®QAR a fast, reliable and high-performance millimeterwave imaging system. Used together with the optional transmitter...
Open the catalog to page 6Spatially resolved reflectivity measurements The reflectivity measurement determines the amount of energy reflected by the DUT. This energy does not pass through the radome and consequently contributes to performance degradation. Reflected signals decrease the performance of the radar and can even interfere with the received signals. High reflectivity can be caused by e.g. material defects, undesired interaction between several layers of materials, excessive amounts of certain materials and foreign objects. The R&S®QAR measures the spatially resolved reflectivity of a DUT by linking the...
Open the catalog to page 7Material transmission frequency response (attenuation) Any radar signal that penetrates a material is split into a reflected, a transmitted and an absorbed part. It is of interest to measure not only the reflectivity but also the transmission properties. The R&S®QAR can be equipped with an optional transmitter module that is placed behind the DUT on the table. The transmitter uses discrete frequency points to cover a selected frequency span. This allows precise analysis of the transmission frequency response. The frequency response delivers detailed information on the RF matching of the DUT...
Open the catalog to page 8Fast and intuitive results The image that the software displays is reconstructed from the spatially resolved results so that the user sees the radome from the radar’s point of view. The data can be saved and analyzed later in offline mode to compare different measurement sequences.
