Abstract
Introduction: With the rise of logistics, navigation, takeout and other industries, location information plays a more and more important role in daily life. It is different from military positioning, which takes high positioning accuracy as the main principle. Due to the need to consider its popularity, civil positioning generally focuses on the principle of economy, and strives to reduce the hardware requirements of the positioning system as much as possible under the condition of reasonable and relaxed positioning accuracy.
Objective: This paper aims to use the received signal strength to locate the emitter signal, and improve the positioning accuracy of the algorithm through continuous iteration and correction, so as to ensure the positioning accuracy on the premise that the positioning method based on RSS does not need additional hardware equipment.
Methods: The algorithm in this paper locates the emitter based on the received signal strength, uses the median weighted filter to collect the emitter power and preliminarily screen out the gross error, then uses the genetic algorithm to select the initial point of the iteration, and uses the improved weighted least squares algorithm based on Gauss Newton iteration to estimate the parameters. Finally, an error correction module is added to further ensure the positioning accuracy.
