Embodiment Construction
[0033] The wireless sensor network sound source target iterative positioning method involved in the present invention comprises the following steps:
[0034] Step A, establish a mathematical model of the attenuation of the sound signal strength with the target distance:
[0035] a i 2 = G i P 0 ′ ( d i d 0 ) n - - - ( 1 )
[0036] where a i Represents the strength of the sound source signal received by the i-th acoustic sensor node, G i is the gain of the i-th sensor node, P 0 ' ...
