The invention relates to a high-precision radio positioning method and a
system thereof based on multidiameter scattering information, which can be applied to various positioning environments, particularly the rich multidiameter conditions with an intense scattering environment and many barriers near a mobile terminal that needs to be positioned, such as urban areas, hilly areas and the like. The method is a high-precision practical
positioning technology and comprises the following steps: firstly, a reasonable multidiameter scattering radio positioning model which is transmitted by non-line-of-
sight electric
waves is established according to the actual communication environment; then the scattering information is estimated by the positioning data of the multipacket and multidiameter scattering information detected by a plurality of sensors; then a group of analog sensors are reconfigured by the scattering information; and finally, at the time of final positioning, a new judgment rule and a new
algorithm obtained by revision and used for the multidiameter scattering information are put forward, so as to realize precise target positioning. The high-precision radio positioning method and the
system thereof can effectively inhibit non-line-of-
sight communication errors, and have the advantages of low cost, low
energy consumption and very high positioning precision.
