Abstract
Today, target detection in Orthogonal Frequency Division Multiplexing (OFDM) Radars is very interesting. Recently target detection in OFDM radars has been reported But in all of them assumed the RCS of target is constant and clutter has Gaussian distribution. However, in this paper, we investigate the effect of target fluctuation (Swerling case II) and Non Gaussian (Log normal) clutter in the OFDM radar performance We assume the fluctuation occurs only between subcarriers. For comparisons, we consider two scenarios We consider the GLR detector for target detection and investigate the target fluctuation on GLR detector performance. We provide a few numerical examples to illustrate the detection performance for moving target under conditions of two scenarios and fluctuating model in presence of Log normal clutter.
