Cross-Layer Interference Modeling and Performance Analysis in FMCW Radar Multiple Access Network

With the increasing density of vehicular radars on the road, interference among vehicular radars is becoming an important problem. In this work, we consider a frequency modulated continuous wave (FMCW) radar multiple access network and develop mutual interference models for analyzing target-ghost classification performance. We next define a cross-layer performance metric called multiple access capacity that is analyzed under a simple random access scheme (un-slotted ALOHA) to obtain system design insights.
