Abstract

The performance of adaptive arrays for jamming cancellation is degraded due to relative angular movements between the array elements and the signal sources in space. We consider small angular variations about the steady state of a linear (power inversion) array caused by either 1) a discrete angular jump, or 2) a continuous angular movement with constant angular velocity. Performance degradation is assessed in terms of the resulting increase in the total output power relative to its steady-state (minimum) value. The results reported are independent of the algorithm used to minimize the output mean square error (MSE) and are supported by computer simulations.
