Simulation plays an important role in analyzing automotive radar system performance. Simulated data can be used as a testbed for algorithm development. It can provide a framework to adjust parameters in support of “what-if analysis” across scenes. In this workshop, we will describe a methodology to simulate high fidelity raw data for an automotive radar where the simulated signal exhibits many necessary propagation effects (e.g, delay, Doppler, micro-Doppler, multipath, weather degradation). RF and antenna components can also be modeled. The fidelity of the scene can be increased with a reduced amount of driving-based data collections.
Traditional arrays consisting of well-isolated elements are usually studied via analytical beamforming techniques. However, with the introduction of 5G networks, phased arrays need to be designed according to strict size and cost requirements, which may result in sub-optimal isolation. Beamforming optimization for such arrays needs to consider the individual element patterns, system S-parameters, varying impedance matching, active reflection coefficients and amplifier characteristics simultaneously, all of which are beyond the scope of classical formulations. In this workshop we’ll study the limits of the classical formulations and go beyond them with numerical techniques, enabling accurate, fast and robust optimization of compact arrays.
This workshop will demonstrate a design-to-test workflow for a COTS phased-array radar system using Analog Devices’ ADAR 1000 beamforming ICs and ADTR1107 Transceiver ICs.
