Stealth design never makes the plane invisible, it just increases the detection distance or the power requirement of the radar. You get relatively long way by simply avoiding corner reflectors. There are rumors that Avro Vulcan used to disappear from friendly radars accidentally just because of that. One of the features that increases stealth is the radar. Because radars tend to show on radar. SR-71 had "side looking radar" which might have been optimized not to show the array towards any hostile ground stations.
