基于DSP的二维CFAR检测快速实现

Abstract

Abstract: Constant false alarm rate(CFAR) detection is an important technique in radar signal processing application,two-dimensional CFAR detection adopts more referenced cells of frequency domain to decrease the false alarm rate.In order to reduce the time overhead of data addressing of the traditional method,a strategy of conversion from space to time is proposed.By scheduling the digital signal processor resource and using some optimization measures,the point-by-point detection is transformed into data matrix block operations,the proposed strategy can reduce the complexity of data management effectively,and the results of realization with measured data show that there are above 8 times improvements,which verifies the validity of the proposed method.
