R&S releases the R&S AREG100A, a automotive radar echo generator

Published time: 2018-08-28

Rohde & Schwarz (R&S) worked closely with the automotive industry to develop a new automotive radar echo generator R&S AREG100A after deep understanding of industrial demand.

This is a decades of experience in the field of millimeter wave technology in the measurement expert R&S. A measuring instrument designed to meet the testing needs of the automotive industry.

R&S introduces the R&S AREG100A, a vehicle-based radar echo generator, a reliable, leading-edge automotive radar sensor production tester.

Radar sensors are an important component of autonomous driving, helping to ensure safe driving. With the gradual development of all phases of autonomous driving, the number of radar sensors per Automotive has increased significantly, and both OEMs and Tier 1 suppliers require reliable test solutions for mass production of safety-related equipment for radar-assisted driving systems.

R&S's newly developed automotive radar echo generator R&S AREG100A is designed for final inspection and inspection of OEM and Tier 1 suppliers. 

Continuous monitoring of quality is essential to ensure that the functionality of the radar sensor is unrestricted and to ensure that the ultimate safety of autonomous driving during the production.

The R&S AREG100A is a customized solution for production line terminals that is reliable. All the requirements of operation are easy to operate.

The R&S AREG100A automotive radar echo generator is primarily used for reliability testing of the 24 GHz ISM band and 77 GHz or 79 GHz E-band radar sensors; it can simulate radar target echoes of up to four fixed distances, The user can specify the required fixed distance in advance and can also configure the doppler shift to simulate the radial movement of the object.

The R&S AREG100A is a future-oriented radar target simulator for testing advanced long-range radars and short-range radars. 

It supports E-band bandwidths up to 4 GHz; if the distance between the RF front-end and the object under test is 80 For centimeters, a radar target with a minimum distance of 4 meters can be simulated. In this way, the R&S AREG100A offers exceptional test flexibility for automotive industry customers.

Due to the rapid increase in the number of safety-related driver assistance systems equipped with radar sensors, European regulators have mandated mandatory testing in the Radio Equipment Directive (RED) to ensure the coexistence and operational safety of automotive radar sensors. In particularly, It is in the aspect of automatic driving.

In order to make the test specified in the RED specification ETSI EN 303396 easier and cost-optimized, the R&S AREG100A provides calibrated input and output ports in the IF band, which can detect the sensor's immunity to interference signals by connecting the RF signal generator. Degrees, with signal and spectrum analyzers, can easily and quickly measure occupied bandwidth and spurious emissions.

In addition, the power meter accurately measures the total radiated power (equivalent isotropic radiated power, EIRP). 

Because the millimeter-wave hardware module at the front of the instrument can be used with the above instruments, only a 6 GHz RF signal generator, a signal and spectrum analyzer, and an 8 GHz power meter are required, no additional millimeters. 

Wave measuring equipment. In order to achieve the high repeatability of the aforementioned test scheme, R&S offers an anechoic chamber that is compact and does not affect the shielding performance.

R&S AREG100A, a radar echo generator from R&S, is suitable for continuous monitoring of line terminal quality, allowing OEMs and Tier 1 suppliers to ensure that the radar sensors installed on the Automotive are functioning properly before the Automotive is on the road.
