FDA-MIMO radar is a new form of radar technology that has a vast range of applications. Jamming is one of the many issues faced by the FDA-MIMO radar, such as deceptive jamming and target detection. A lot of work has been done in the fields of jamming and anti-jamming with FDA-MIMO radar. This paper introduces a non-linear SMA-FDA MIMO radar. Modified SMA has been proposed and implemented, which was never used in the radar application before it was used in the biological fields. Anti-deceptive jamming has been performed over the FDA-MIMO. Desired targets are being detected successfully. Simulation results are presented to show the efficiency of the proposed algorithm.
