For our November 2013 issue, we return to the topic of radar signal processing. We had last covered recent patents in the area of radar signal processing in November 2011. Below, we consider several recent inventions in applications that involve processing of radar, lidar and millimeter wave signals. Different from our previous coverage of radar-related inventions which dealt primarily with airborne or satellite platforms, this selection is biased more toward civilian (e.g. automotive) applications.
