If close enough, direction finding: target coordinates direct to counterbattery centre and the jammer (or at least: its antenna system) would be pounded flat in minutes. (Toward the end of WW1 the German artillery were forbidden from firing singly due to the efficiency of allied Sound Ranging - fire would be returned before the German shell had landed. This was with _manual_ systems!)
