In this paper a generic 2D Ray tracing channel modeling tool is proposed. The proposed tool has been optimized for GPU architecture. Two examples for different types of applications have been presented and used to profile the tool. Comparative results have been presented for different parameters and examples. Due to its high speed, the proposed tool is useful for system optimization for large EM problems such as automotive radar application.

“…Highfrequency approximations, like geometric optics in combination with the uniform geometrical theory of diffraction, are currently practicable methods to calculate the wave propagation in complex large-scale environments at high frequencies with a reasonable computational speed [12]. Such wave propagation models can further be used in system simulations for communication and radar applications in several levels of detail [8], [9], [13]- [15].…”

This paper provides qualitative and quantitative values for the received interference power at the antenna ports of automotive radars as well as the probability of their occurrence for actual and future, not yet measurable traffic scenarios on main roads. The influence of the environment, the road traffic behavior, and the radar penetration rate for a defined antenna configuration can be observed. The basis for the analyses are ray-tracing based simulations in order to achieve adequate predictions for the received power levels due to multipaths. The results show that for a radar penetration rate of 100%, the difference between the strongest overall incoherent received interference power level and the level that is received in 90% of the time is up to 7 dB, dependent on the antenna placement and the environment.

“…With the FMCW and antenna array, the radar can provide the distance, azimuth and velocity of on-road targets in low cost and simple hardware. The radar antennas receive energy reflected at the vehicles and the guardrails in highway scene [5]. Limited by the antenna aperture, the radar images have low angle resolution, causing difficulties to recognize the on-road vehicles which are similar to the guardrails and other targets in the image.…”

This paper deals with the road and vehicle detection problem in highway scene for automotive radar which uses frequency-modulated continuous-wave (FMCW) signals and antenna array. Due to the automotive radar's low angle resolution, targets such as guardrails on road edge interfere with the vehicle detection and bring difficulties to the distance-velocity decoupling. We proposed an approach with Hough transformation and image matching for the road and vehicle detection. The interference of outroad targets is suppressed and the decoupling is achieved with low complexity. Specially, based on the road boundary model, the road boundary can be achieved by a curve Hough transform. Then, the on-road vehicles are detected and the distance-velocity decoupling can be solved by target region image matching with a total variation minimization method. Our new algorithm has a low computational complexity, and is validated by field experimental results.
