An approach to improve airborne radar performance in clutter environment

This paper introduces a technique for clutter reduction in airborne radar systems. This technique is based on the fact that the nature of the clutter and target are different in the sense that the clutter returns are randomly distributed from scan to scan, while those for target have a deterministic behavior. An algorithm is developed to discriminate between target and clutter returns from one scan frame to another, where 3 out of 5 criteria used to correlate successive scan frames were adopted. A series of simulation experiments are carried out where the algorithm is applied on range-scan frames. The results show a reduction in P_fa with an increase in P_D for different target scenarios
