• We report the benefits of non-Gaussian noise to narrowband weak signal detection.
• We achieve the optimal detection probability by tuning noise level.
• Tuning noise is superior to optimizing detector threshold for the Rice noise model.
In an ad hoc suboptimal detector, the benefits of non-Gaussian noise to narrowband weak signal detection are demonstrated. Particularly, for a noise envelope with a Rice distribution, we can improve the detector performance by tuning threshold parameter but keeping noise level, or increasing the noise level for a fixed threshold. It is verified that, under certain circumstances, the optimal detection probability achieved by tuning noise level is superior to that obtained by optimizing the detector threshold.
