Sansürlü Hücrelerin Ortalamasına Dayalı Sabit Yanlış Alarm Oranı İşlemcileri

Abstract

In this study, the performance of constant false alarm rate (CFAR) processors and censorship techniques developed to increase the probability of detection in a nonhomogeneous environment was investigated. False alarm and detection probabilities of the censored cell averaging false alarm rate (SHOSYAO) processor whose performance was investigated were calculated analytically and its performance analysis was conducted analytically by censoring different number of samples together with other censorship techniques given in the literature. The performance analyzes of different censorship techniques for non-homogeneous environments were made comparatively by using the threshold values found for the homogeneous environment and compared with the detection probability of the CA-CFAR processor on computer simulations. The cases where the interfering targets in the non-uniform environment have the same and different signal-to-noise ratio as the tested target were investigated.
