Recently, in response to a question on CFAR algorithms on a Linkedin group (sign-in required), I posted a list of CFAR schemes proposed and used so far within the radar community. Later, I thought it would be pertinent to discuss some of the CFAR related concepts in this blog. Unfamiliar readers of the basics of detection theory may please consult a few initial chapters of [1]. The hardware implementation of many CFAR techniques is a challenge to radar engineers. A few years ago, I authored a paper [2] on the FPGA implementation of OS-CFAR where the basic idea derives from preserving the traditional running summer architecture of CA-CFAR implementation.

Thanks. Yes, pun intended 🙂
