This Report analyses the performance of the Coherent NAVICO radar system in heavy sea clutter conditions. The performance of the system are analysed in term of Receiver Operating Characteristics (ROC), that is in terms of Probability of False Alarm and Probability of Detection. The Report is organized as follow. Section 1 introduce the Clutter and Target signal models, in particular the heavy coherent sea clutter is modeled with an Auto Regressive process whose samples belong to a coherent K distribution while the target echo is generated according to the well known Swerling I model. Section 2 describe the flow diagram of the coherent NAVICO radar receiver, each block of the receiver flow chart is described and compared with the optimum CFAR detector in Gaussian clutter. The performance of the system are reported in Section 3 while Section 4 describes the Matlab script functions that has been created to model and analyse the system.

Abstract
This Report analyses the performance of the Coherent NAVICO radar system in heavy sea clutter conditions. The performance of the system are analysed in term of Receiver Operating Characteristics (ROC), that is in terms of Probability of False Alarm and Probability of Detection. The Report is organized as follow. Section 1 introduce the Clutter and Target signal models, in particular the heavy coherent sea clutter is modeled with an Auto Regressive process whose samples belong to a coherent K distribution while the target echo is generated according to the well known Swerling I model. Section 2 describe the flow diagram of the coherent NAVICO radar receiver, each block of the receiver flow chart is described and compared with the optimum CFAR detector in Gaussian clutter. The performance of the system are reported in Section 3 while Section 4 describes the Matlab script functions that has been created to model and analyse the system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
