| Abstract: | Slow and fast thresholds CFAR processing algorithms are studied.Aiming to slow threshold CFAR circuit model,logarithmic subtract is used to improve efficiency instead of division operation.To the edge effect problem exists in fast threshold CFAR processing circuit model,the solution of selecting the maximum in average from both side units is adopted.And this makes the radar detection system be in constant false alarm. |
