  4. Abstract:
  5. CFAR detector is an essential component in any radar system. This component ensures that the system may not be overloaded by false targets. In the past it was common to model the interfering signal (clutter) in a radar system with a Rayleigh distribution. But as a progress in the radar systems, nowadays the Rayleigh model is insufficient, therefore some other models such as Weibull and lognormal are proposed and CFAR detectors for these models are developed through the papers. But majority of these proposed CFAR detectors are derived for single pulse operation. When more than one pulse exists, it is proposed to use binary integrator to improve the performance. It is mentioned through literatures that binary integration leads to some losses. But alternative solutions are not discussed widely so much. In this paper we will introduce some soft rule for combining the statistic of different pulses in a single decision structure and will show out performance of this method in comparison with binary integration. © 2007 IEEE
