Constant False Alarm Rate (CFAR) Detection in Weibull Environment

In this work, the performance of N pulse radar receivers which use Post Integration (PI) and Binary Integration (Bl) algorithms is analysed in homogeneous Weibull environment. It is assumed that the shape parameter of the Weibull distribution is known a priori. If the scale parameter is known a priori, PI and Bl receivers, otherwise the same receivers integrated with CFAR processor which estimates the scale parameter are considered. The performance of the considered models are analyzed and compared with different shape parameters. For PI-CFAR model, the sensitivity of the model is analyzed for the case when the shape parameter value of the real data is different from the design value.
