    SD was a long wave metric radar, whose range & bearing discrimination were both totally inadequate for a torpedo attack fire control solution. The later SJ set was 10 cm, which was much more accurate, so could be used for torpedo attacks. As I understand it, the initial detection here was by radar, but the submarine then closed for a conventional attack.
