“…10 In the literature, different objective functions were proposed for the POMDP-based sensor management, for example, the Kullback-Leibler discrimination, 9 posterior expected number of targets, 11 the Rényi divergence , 12 and the posterior cardinality. 13 However, no matter what objective function is used, POMDP-based sensor management is essentially a global combinatorial optimization problem that is extremely challenging especially when the sensor network is quite large, unless only one sensor is selected in use as illustrated in the study by Gostar et al 14 A spatial nonmaximum suppression heuristics has been proposed recently to alleviate this issue, 15 whereas it suffers from a tuning parameter of the suppress gate. Ma et al 16 proposed a suboptimal solution of the POMDP-based sensor control which is not suitable for sensor selection problem.…”
