Okay, so after looking through, the only Semblance I've found that really fits the radar/sonar bill so far is ACW's Semblance called "Audio", which as the name suggests, is heavily sound-based. There's also "Track" from Spirited, but that one is extremely vague and wide-reaching, plus it's not really a "sonar" effect.
