Location Method of GNSS Jamming Source Based on TDOA Passive Detection Technology

Abstract

Aiming at the problem of jamming source location in satellite navigation system, this paper introduces a method of GNSS jamming source location based on TDOA passive detection technology, analyzes the influence of station location error and array form on jamming source location accuracy, and presents an error processing method which is easy to realize in engineering. By deriving the error transfer equation of TDOA, introducing the error deterioration factor and relative positioning factor as the system performance analysis index, the effect of $\alpha-\beta$ filtering on positioning error is given through simulation.
