Abstract: In this paper, a novel approach of combined Cell Averaging-Constant False Alarm Rate (CA-CFAR) detector and Sidelobe Blanking (SLB) system is proposed. CFAR based threshold estimation using a Generalized Automatic Sliding Window technique (GASW) is proposed to reduce the memory access and exploits pre-computed values for setting the new threshold for adjacent cell. The designed architecture is fully reconfigurable in terms of the number of reference and guard cells as well as the sampling frequency and the coherent processing interval (number of integrated pulses).
Keywords: CA-CFAR, SLB, GASW, Architecture, Reconfigurable, Generalized.
Scope of the Article: Low-power design
