An Analysis of CFAR Thresholds and Scale Factors with Window Effects in Pulse Compression

This paper presents an analysis of the window effects on the constant false alarm rate (CFAR) techniques. In this research, the scale factors for the robust CFAR detectors, which are not explicitly defined by theoretical equations, are derived by utilizing the Monte Carlo method. To ensure the reliability of the implemented Monte Carlo simulations, we compare the scale factors between the theory and the simulations in cell averaging-CFAR (CA-CFAR). The need for a credible adjustment of the scale factor to achieve a consistent false alarm probability is confirmed through simulations that investigate noise distributions and CFAR thresholds with various windows in pulse compression.
