Design requirements for 24 GHz and 77 GHz automotive radar sensors are becoming more stringent as consumers increase demand for applications like blind spot detection (BSD) and lane change assistance (LCA). In turn, the engineering departments at Tier 1 suppliers like Delphi, Autoliv, and Continental are advancing technology in order to win bids from OEMs like BMW, Audi, and Chrysler.
Simulation technology has also advanced to meet design requirements. Remcom offers an integrated approach from sensor design to drive test scenarios.
Sensor Design and Placement
Remcom’s time-domain electromagnetic simulation software, XFdtd, is a proven tool that promotes the rapid development of automotive radar sensors. Using simulation, RF and application engineers are able to analyze the far-field radiation characteristics of their antenna, minimizing the number of prototypes built and tested in a lab.
Engineers use XF for various aspects of sensor development including:
Drive Test Scenarios
Remcom’s ray-tracing simulation software, WaveFarer, augments repeatable track tests and drive scenarios. Simulating raw radar returns from a set of scenarios allows engineers to gain insight into a design, placement, or target identification algorithm without the overhead required to install prototypes and take measurements.
Drive test simulation is a powerful tool that benefits engineers of various disciplines, as illustrated by the following examples:
