Abstract :
The problem of inevitable frequency bandpass disparity (FBD) for an adaptive array system in an actual non-uniformity circumstance is researched in this paper. From different forms of characteristic analysis, the frames of the eigenvalue and power spectrum are developed, expressions of the adaptive filter characteristics and system improvement factor are also obtained. Such works are confirmed by computer simulation and have provided several feasible references in performance improvement for adaptive array system in circumstances of nonuniformity
