Hi all
I am working on beam forming of high frequency (>400 KHz) linear array for imaging sonar. I have gathered sensor data of 80 channel linear array sub merged halfway in 8 m deep water tank with a transmitting probe 6 m away from it at same depth. I recorded multiple pulses and perform offline analysis on it. The problem i am facing is very high side lobe levels in a beam pattern developed using recorded data. Can any one kindly guide me what could be possible causes of higher side lobe levels?
Thanks & Regards
