Challenges for non-cooperative target identification in a bistatic radar configuration

NCTI ("Non-Cooperative Target Identification") in a monostatic radar configuration has been investigated extensively within the past years but classification in a bi-/ multistatic configuration does not seem to have obtained much attention to date. Some differences between monostatic and bistatic radar pose challenges to NCTI, which have to be met especially if monostatic and bistatic data or data with differing bistatic angles are to be compared. In this paper these challenges will be discussed and some classification procedures will be introduced. By means of data from turntable measurements of three distinct ground vehicles, which have been conducted at Fraunhofer FHR, the influence of different radar constellations on classification performance will be described.
