Description
Summary:In a radar the performance of signal detectors is seriously degraded by arrival of impulse noise that extremely worsens their detectability characteristics. There are many papers, in which different Constant False Alarm Rate (CFAR) detectors have been analyzed in the presence of randomly arriving impulse interference, described as Poisson pulse sequences. In this paper the randomly arriving impulse interference is mathematically described as Binominal pulse sequences. This model of impulse noise is used for numerical analysis of two types of CFAR pulse detectors (CACFAR and EXC CFAR). The detectability of these pulse detectors is numerically analyzed in the presence of Poisson and Binomial impulse noise. Therefore, the proposed detectors can be used in different radar systems and secondary applications of communication technologies.
