| Abstract: | The constant false alarm rate(CFAR) detection of radar signal plays an important role in radar signal processing. The principle of object detection of a certain radar is introduced, the influence of threshold coefficient on object detection is analysed,and a method to determin the threshold coefficient based on noise sampling is proposed. Finally,the feasibility of the method is verified through simulation. |
