Soderberg, an ARRL member, was one of the inventors of the spherical array and its associated electromechanical compensator that was the primary acoustic (sonar) sensor subsystem on three generations of Navy nuclear attack and fleet ballistic submarines. He was also a key member of the Underwater Sound Laboratory (USL) engineering team that developed sonar and related systems for the submarines. According to friends, he was walking the hills for miles with his German shepherd and working CW just days before his death. |
