Distributed Sensor Local Linear Fusion Detection of Weak Pulse Signal in Chaotic Background

Table 3

detection effect under different models.

Model	Index
	Accuracy	Precision	Recall	F1 score
DS-LLAR	0.9982	0.5833	0.7778	0.6667
DS-LM	0.9977	Nan	0	Nan
Chaos unconsidered	0.1062	0.0020	0.7778	0.0039

Note: Nan is generated when the denominator is 0, because the system does not detect the correct signal.
