While propagation effects can thwart signal detection, they can also enhance the prospects for detection.
Academic text (1999) -
The technique is a modified version of a method in signal detection which can pick a signal out of random noise if the shape of the signal is known—that is, when you know what you're looking for.
Academic text (1996) -
In counterbalanced conditions of waking and hypnosis, subjects were given 36 signal detection trials, consisting of 12 strong signals, 12 weak signals, and 12 "no" signals. No differences were observed in the waking condition between low, medium, and high hypnotizables on strong and weak signal trials.

Morphology
The meaning is directly compositional: it denotes the act or process (detection) of a signal, so a learner who knows 'signal' (a transmission) and 'detection' (the process of discovering or sensing something) can infer the phrase. This noun-noun combination follows a common cross-linguistic pattern for naming processes and is therefore immediately understandable even if technical details (e.g. in telecommunications) require more domain knowledge.
Etymology
Signal detection comes from the image of trying to find a faint signal, like a small light or quiet beep, while everything else makes noise, for example hearing your phone ring in a crowded room. The word detection is about deciding if that sound or light is real or just 'noise', so the phrase means 'deciding whether a signal is present'.
