摘要

This memorandum presents some computed results of the effects of inoperative staves in the presence of a dome on the nearfield and farfield patterns of the AN/SQS-26. Self and mutual stave impedances are given. The results are obtained from equations describing a two-dimensional model composed of a cylindrical baffle (transducer) with radiating strips (staves) enclosed in a thin, concentric shell (dome). The results show that for both the Track and Bottom Bounce Beams the dome increases the peak pressure in the nearfield as compared to that of a bare transducer. The inoperative staves produce additional non-uniformity of intensity across the major lobe in the farfield pattern of the Bottom Bounce (45 deg) Beam. The dome increases the level of the side lobe structure, further degrading the farfield pattern. The dome causes an increase in the magnitude of most stave impedance but reduces the real part of self impedance. (Author)
