MULTIPLE TARGETS DETECTION AND LOCALIZATION BASED ON BLIND ESTIMATION IN WIRELESS SENSOR NETWORK
Peng Zhang, Xiaoyong Deng, Huimin Wen, Jifu Guo · 2011
Observations of sensors are modeled as mixed signals in multiple targets scenario. Each element of mixing matrix represents the power decay of a pair of target and sensor, and each column preserves the waveform formed by the corresponding target respectively. Making use of blind estimation algorithms, we get the estimation of mixing matrix. Target locations are then estimated using the least squares method.
