Abstract
Wireless signal location technology is one of the key technologies of the electromagnetic spectrum detection system. This paper proposes an RSSI (Received signal strength indication) localization algorithm based on electromagnetic spectrum detection, which uses self-organizing network to realize data acquisition and data transmission of detection nodes; In order to reduce the error of the RSSI ranging technology on the positioning accuracy, the number of appropriate detection nodes is selected, the RSSI value is averaged, and a large amount of sample data is analyzed to establish an optimal signal attenuation model; The least squares method is used to transform the nonlinear function described by the RSSI localization problem into a linear estimation problem for precise positioning. The simulation results show that the verification results of simulation data are consistent with those of measured data in positioning accuracy.
