The software pipeline realization of CFAR based on DSP

Constant False Alarm Rate (CFAR) algorithm is an important technology of radar system. It can provide optimal signal detection performance via maintaining a constant false alarm rate. However, the computational workload of estimating the clutter power of every data unit can be high. Thus, a software pipeline method for CFAR on the Digital Signal Processor(DSP) of TI´s latest series C6000 family is proposed in this paper. Compared with non-optimized CFAR algorithm, software pipeline operation can achieve better performance and 41x improvement on instruction cycle.
