Abstract
In this paper a procedure which filters out roughly half of the array manifold errors for approximately centro-symmetric arrays is described. The procedure-subspace domain forwards-backwards (f/b) averaging-improves the performance of subspace based direction finding (DF) algorithms such as MUSIC and ESPRIT. Experimental data from the Mountaintop radar system are used to confirm the theoretical results
