i believe there is a special ability value named SonarContactsAsVisual.
if you assign that to a Special Ability, typically Ability-Expert-Sonarman, and then assign the special ability to a crewman, then the icon remains on the screen when you submerge...as long as it is still detectable by your hydrophone.
