OTSL Announces State-of-the-Art Millimeter Wave Radar Simulator for Autonomous Driving


– Super parallel optimization improves simulation performance more than 10 times –

NAGOYA, Japan, June 17, 2022 /PRNewswire/ — OTSL Inc., a developer and marketer of short-range wireless and in-vehicle systems, has announced a new real-time 3D millimeter wave radar simulator for autonomous driving (*1), AMMWR2 ( Advanced Millimeter Wave Radar Simulator 2). Since introducing AMMWR to the market in 2017 as the world’s first sensor simulation software for autonomous driving that enables real-time dynamic simulation, OTSL has continued to invest aggressively in its development. With the announcement of AMMWR2, OTSL demonstrated the leaps in functionality and performance made in this development. This product is expected to be marketed worldwide by the end of this year to automakers, system vendors developing, designing and producing vehicle sensors, and semiconductor manufacturers developing sensors.

“With the global advancement in the application of autonomous driving, expectations are rising for advanced simulation technology capable of creating a virtual reproduction of all kinds of driving conditions and verifying and validating safety and accuracy. However , the current autonomous driving vehicle only has Level 2 or Level 3 operation according to SAE international standards,” said Shoji Hatano, CEO, OTSL and OTSL Germany GmbH. “In order to achieve fully autonomous driving through the system monitoring, level 5 of the standards, it is essential to include the simulation of potential accidents caused by faults of electronic devices and failures of sensors. AMMWR2, announced on June 17is the only millimeter wave radar sensor simulator that covers from the electronic device level, including semiconductors and sensors, to the simulation domain of autonomous driving (AD) and advanced driver assistance system. driving (ADAS). »

AMMWR2 uses the ray tracing method (*2) using in the field of optical simulation and unique reflection / diffraction models, applying a dedicated computer-generated three-dimensional map from Unreal Engine 4 (EPIC Games, Inc .) implementation of reflection and diffraction models of roads, roadside trees, street lights, traffic lights, signs and others to achieve real-time simulation of dynamic objects. The development of original measurement methods and the creation of reflection models from the data obtained by the measurement allow an accurate simulation of how radio waves from the radar are reflected, even taking into account the shapes and materials of vehicles, pedestrians, traffic lights, signs and other objects. Through an enhanced partnership with COSIDE(R) (*3), a SystemC AMS design and simulation tool from COSEDA Technologies GmbH for semiconductors supporting design from circuit design down to the design level of the system, an environment can be created in which the simulation can be done entirely in software without the need for hardware, such as sensors or electronic control units (ECUs), or even the vehicle itself.

AMMWR2 offers the following major update. These performance and feature enhancements will further shorten development and test times for manufacturers working on self-driving technologies.

  • Acceleration of the simulation engine thanks to internal code optimization and super parallel processing techniques. This improved the performance of ray-traced simulations by a factor of 10 or more.
  • By strengthening the partnership with COSEDA Technologies GmbH which develops the SystemC AMS COSIDE(R) design and simulation tool, various radars can be used as custom models in addition to the unique radar models based on automotive radar that Tier-1 provides with OEMs, including the FR5CPEC from Bosch and Continental ARS540.
  • AMMWR2 now supports integration with the open-source CARLA simulator, which is widely used for the development and testing of autonomous driving algorithms.

To strengthen its COSMOSIM(R) product family of real-time 3D sensor simulators for autonomous driving, including the flagship AMMWR, OTSL has created a local entity at Munich, Germanyin October 2019, where it relocated its development and sales center. In the future, OTSL will continue to expand its business globally and help create superior simulation environments for autonomous driving.


(*1) Millimeter Wave Radar: Technology that measures the distance, direction and size of an object by beaming radio waves towards the object and measuring the reflected waves. The waves are radiated in the millimeter wave band, with a wavelength of 1 mm to 10 mm and a frequency of 30 GHz to 300 GHz.

(*2) Ray tracing method: A method based on geometric optics, tracing light rays and electromagnetic waves to draw images observed at arbitrary points.

(*3) COSIDE(R): An “Electronic System Level Design” tool, developed by COSEDA Technologies GmbH, enables customers to optimize their advanced and complex designs faster, more efficiently and at lower cost.
