Radar Solution for End-of-Line and PTI Tests
03 October 2025 - At the European Microwave Week (September 21 to 26, Utrecht), dSPACE demonstrated a new radar solution for functional testing of radar sensors. The DARTS ARROW has been specially developed for use in end-of-line tests and periodic technical inspections (PTI) of radar-based driver assistance systems. The compact radar target simulator is efficient and easy to use and simulates the range, speed, and radar target cross-section of a radar target in dynamic scenarios.
The new solution covers a frequency range from 76 to 81 GHz and offers a customizable bandwidth of up to 5 GHz. It enables the simulation of distances of up to 500 meters in steps of less than 7 cm and at speeds of ±700 km/h. Depending on the application, the front end can be configured as monostatic or bistatic.
This makes the robust and cost-effective system ideal for validating safety-relevant driver assistance systems such as emergency braking, lane departure warning, and distance control assistants. By realistically simulating traffic scenarios under controlled conditions, sensor errors can be detected and the functionality of safety-critical assistance systems can be ensured over the entire lifecycle.
As part of the revision of the EU Roadworthiness Package, the EU Commission recently proposed carrying out regular checks on driver assistance systems in order to achieve greater safety. A large-scale test of driver assistance systems by the Chinese car portal Dongchedi also underlines the need for regular checks. The driving tests produced sobering results – there were numerous crashes.
