Abstract
It is shown that if a narrowband adaptive array is partitioned and processed as a cascade of adaptive arrays, computational complexity is reduced and performance is only slightly degraded. The sample matrix inversion (SMI) and covariance matrix estimation are discussed. Cascade SMI complexity is examined. Simulation results are presented.>
