Adaptive radar detection of fluctuating targets in autoregressive interference

In this paper, an adaptive detection scheme for fluctuating targets with a swerling I model in AR interference is presented. Since the proposed detector uses more information from the target signal in its structure, it has better performance compared with those detectors which do not use the target amplitude model. Performance improvement of this detector compared with the previously AR model based adaptive detector (ARGLR) is shown by simulation results. Besides, another detector is proposed for the known amplitude situation whose performance can be used as an upper bound for all similar detectors
