This paper describes the result of present examine at DREA during which suggestions of optimal array processing are being utilized to lively sonar. we're providing those effects on the complicated learn Institute so one can illustrate a few real purposes for such processing and to indicate the various useful issues which come up in actual platforms. specifically, the paper issues the issues which come up while the person sensor parts have a classy directivity development themselves. this can be a universal phenomenon in lively structures the place the receiving sensors are complicated resonant constructions and are housed in a dome or towed physique offering numerous baffling and diffraction results. so much remedies of array processing ponder perfect parts that have good behaved directivity homes and are obvious to the sector. the result of this paper convey that the place those houses usually are not met, cautious in situ array measurements are required, or even with such measurements useful array earnings will not be pretty much as good as predictions in accordance with perfect sensors.
