AI Technical Summary

Benefits of technology

This patented technology allows for testing algorithms used by autonomous vehicles (AVs) on their own without requiring human intervention during its operation. It uses simulated radars that are generated from simulations made up of small units called cubelets - which represent different parts of an AV's sensing capabilities. By comparing these results with actual sensor readings they help identify any issues affecting how well it works overtime.

Problems solved by technology

This patents describes how radar technology works well when installed on different types of equipment such as car sensors, boats navigators, drones, etc., but there may still exist challenges associated with maintaining sufficient training period during tests due to high costs involved. Additionally, some important scenarios require specific conditions set by engineers who cannot access realistically relevant data sources like road signs or obstacles themselves.

Abstract

Methods and systems for testing automotive radar by using a simulated radar data cube simulator are disclosed. A simulated radar transmission waveform is defined based on the expected radar performance. A virtual real-world scene comprising one or more virtual target objects is constructed. The virtual target object simulates the reflection and scattering characteristics of the input radar waves of the real world object. The operation of radar transmitting and receiving channels including an antenna array and free space propagation is simulated to obtain the simulated raw radar data, and data processing is performed on the simulated original radar data to establish a simulated radar data cube. A radar perception algorithm is tested by using the simulated radar data cube.
