Embodiment 1
[0068] The present invention provides a passive positioning method based on spatial migration compressed sensing, such as figure 1 As shown, the passive positioning method based on spatial migration compressed sensing includes:
[0069] Step 1, respectively deploy sensor nodes in the sample area and the area to be monitored;
[0070] Step 2, collect the RSS matrix at the reference position in the sample area and the area to be monitored by the sensor node;
[0071] Step 3, obtaining a transfer function according to the RSS matrix of the sample area and the area to be monitored;
[0072] Step 4, collect sample RSS values in the sample area through the sensor nodes, and combine the sample RSS values into a perception matrix;
[0073] Step 5, collect the positioning RSS value in the area to be monitored through the sensor node, and combine the positioning RSS value into a measurement vector;
[0074] Step 6: Migrate the perception matrix of the sample area and the measurem...
