Abstract
This work is carried out as a result of Royal Canadian Air Force’s requirement to deploy a modeling tool for evaluation and prediction of wind turbine interference to its legacy AN/FPN-504 and recently acquired Cassidian ASR NG radars. This Letter describes the modeling of a sub-component of the Radar Obstruction Evaluation Model/Simulator (ROEMS), namely, the cell-averaging constant false alarm rate (CA-CFAR) detector. The CA-CFAR detector model is based on Gandhi and Kassam’s closed-form analytical formula [1], originally derived to predict CA-CFAR performance under target-like interference in one or more of its reference cells. The original formula is applicable only to the single pulse case, with no pulse integration applied. In this Letter, the model is extended to include cases of coherently and non-coherently integrated pulses for improving signal-to-noise ratios (SNR).
