Abstract

A new algorithm using the Householder transform to directly update an inverse data covariance matrix is examined for adaptive phased array radar (APAR) problems This algorithm is shown to operate very efficiently on parallel matrix-vector processors without the need for costly vector outer products. The processing accuracy requirements for this algorithm are shown to be roughly half that of more conventional direct approaches, which nearly doubles the processing speed. We investigate the performance of this algorithm with various jammer scenarios, and incorporate a joint jammer-clutter reduction architecture using a displaced phase center antenna (DPCA).
