Automotive radar test chamber offers temperature option
The R&S ATS1500C automotive radar test chamber from Rohde & Schwarz offers a new temperature test option and a new feed antenna. These additional features enable temperature-controlled measurements in a wide temperature range as well as parallel access to both polarisations, increasing test efficiency and flexibility.
The movable, compact antenna test range (CATR) -based antenna test chamber is designed to eliminate ghost targets within the chamber during target simulation tests and includes a positioner for angular measurements.
The R&S Arc-Temp temperature test option creates a temperature-controlled environment for the radar under test and supports a wide range from -40 to +85 degrees C. The heated or cooled air is provided by an external thermal air stream system that supplies the air to the temperature bubble mounted on the positioner. This changes the temperature without affecting the chamber’s measurement performance which makes it possible to automate measurements at different temperatures without a separate climatic chamber, which increases radar testing speed.
In addition, the new R&S ARC-FX90 universal feed antenna, which supports 60 to 90GHz, can be added to the R&S ATC1500C. The antenna includes an orthomode transducer, which enables parallel access to vertical and horizontal polarisations.
With these new options for the R&S ATS1500C, developers can characterise RF transmitters, calibrate antenna manifolds, measure antenna patterns, test robustness against interference, check compliance with regulations such as ETSI and FCC as well as plan testing and calibration procedures for later mass production. The R&S ATS1500C is used as a reference environment before porting the procedures to a production tester.
In combination with the R&S AREG800A automotive radar echo generator, the R&S ATS1500C is intended for automotive radar module development, validation, calibration and compliance testing.
The R&S ARC-FX90 universal feed will be available at the end of 2022 and the R&S ARC-TEMP temperature option in Q1 2023. Both options are hardware extensions and can be retrofitted to the R&S ATS1500C.
The ATS1500C will be shown at EuMW in Milan, Italy (27 to 29 September 2022) at booth D18.
