Period-Time Parametric Identification Method for Solving Location and Navigation Tasks

With regard to location and navigation tasks for single-position passive observer, a bearing-free method for identifying parameters of a polynomial model of object motion has been developed taking into account evolution of the discrepancy between the periodic radiated and received quasi-periodic signal. The passage of a signal in an arbitrary physical environment is considered, at the same time, knowledge of the period of the emitted signal and assessing the current Doppler frequency are not required. The method is based on counting the number of periods of the received signal in a given surveillance intertissue. The issues related to the analysis of the resulting discrepancy by the observability of the method and its accuracy characteristics are considered. Useful practical recommendations and an illustrative context are given.

Automated summary

This article introduces a bearing-free method for location and navigation tasks, which identifies parameters of object motion by considering the evolution of discrepancy in periodic radiated and received signals. The method allows signal transmission in arbitrary physical environments without requiring knowledge of signal period and current Doppler frequency. The observability and accuracy characteristics of the method are discussed, along with practical recommendations and an illustrative context.
