Radar Target Simulation Based on Measurement Data

The repeatability of radar sensor tests is of high importance, in order to allow for a better comparability. Guaranteeing consistent test conditions is therefore essential. This article describes a radar target simulator able to simulate a traffic scenario for chirp-sequence frequency modulated continuous wave radar sensors, based on measurement data. First, the system setup is briefly presented, that is used to generate the targets, afterwards the major challenges and required signal processing steps are laid out. Finally, a comparison between the original measured scenario data and the replayed version is conducted.
