So what's the point? Range without direction? You know it's there - but you don't know where? You happen to have an example of this?
I do, since I worked on them in a past life. The radar that was used to provide distance information to day-fighter optical gunsights provided only distance. The location was provided by the optical gunsight. An annunciator light would light when the ranging radar had a lock-on. There was no radar display. In radar parlence, this is known as an "A Scan" radar.
