R&S launches a reliable and future-proof production tester for automotive radar sensors

Automotive radar sensors are one of the key components for autonomous driving development and the number of radar sensors per vehicle is rising significantly. Both OEMs and Tier 1 suppliers need reliable test solutions, suitable for mass production, for a large number of safety-related radar-based driver assistance systems.

Tailored to the automotive industry’s test requirements, Rohde & Schwarz has developed the new R&S AREG100A automotive radar echo generator specifically for final test and inspection on OEM and Tier 1 production lines.

According to the firm, the R&S AREG100A offers continuous quality control at the end of the production line. This enables OEMs and Tier 1 suppliers to ensure the unrestricted functionality of radar sensors for installation in vehicles, even before they are driven.

R&S AREG100A Automotive Radar Echo Generator

The solution reliably tests radar sensors in the 24 GHz ISM band and in the E band at 77 GHz or 79 GHz. It simulates echoes of up to four artificial target objects at fixed distances. User-configurable Doppler offsets can optionally be applied to simulate radial movement of the objects. Customers can specify desired fixed distances at the time of order.

The R&S AREG100A is a future-proof solution for testing advanced long-range and short-range radars. It supports bandwidths up to 4 GHz in the E band and can simulate objects at a minimum distance of 4 m if the distance between the frontend and the DUT is 80 cm. Thus, it offers its customers an extraordinary degree of test flexibility, from simple to complex, said the firm.

The European regulatory authorities have stipulated mandatory tests in the Radio Equipment Directive (RED) to ensure safe operation and coexistence of automotive radar sensors, particularly with respect to autonomous driving.

For easy, convenient and cost-optimized execution of the tests specified in the RED standard ETSI EN 303396, the R&S AREG100A provides calibrated input and output ports in the IF band. The immunity of the sensors to interference signals can be checked with a connected RF signal generator. The occupied bandwidth and spurious emissions can be measured easily and conveniently with a connected signal and spectrum analyzer. And the total radiated power (equivalent isotropic radiated power, EIRP) can be determined very precisely using a connected power meter.

All that is needed is an RF signal generator up to 6 GHz, a signal and spectrum analyzer, and a power meter with 8 GHz bandwidth, since the millimeter wave hardware of the frontend can be used with all of these instruments. No additional millimeter-wave T&M equipment is needed to carry out the tests, according to R&S.

The R&S AREG100A can be ordered now from Rohde & Schwarz. Purchasers of a new R&S AREG100A benefit from a three-year warranty.
