Yes, that is about it: coherent integration = voltages (currents) are added, noncoherent integration = powers are added. For example, say the transmitted radar pulse is $$p(t)cos(\omega t) \text{ where } p(t)=1, \text {when } |t|<T_p/2 \text { and } 0 \text { otherwise}$$. Now the radar receiver gets this pulse with some unknown phase and amplitude ...
