Abstract

The present disclosure provides a systems and methods for processing radar data. In one example embodiment, a first digitized radar signal of an environment is received from a first radar module and a second digitized radar signal of the environment is received from a second radar module. The first digitized radar signal and the second digitized radar signal are processed, via an electronic processor, to determine a set of correction parameters. A first corrected radar signal is determined by applying the set of correction parameters to the first digitized radar signal. A second corrected radar signal is determined by applying the set of correction parameters to the second digitized radar signal. The first and second corrected radar signals are combined into a combined radar signal. A scene representation of the environment is determined based on the combined radar signal. The scene representation is provided to an autonomous driving system.
