Determination of Location of the Radiation Source

Unwanted radio interference can disrupt critical communication channels, posing safety risks in crucial applications. Rapid and accurate localization of interference sources is therefore essential. This paper focuses on trilateration-based localization, where the position of a radiation source is estimated from time-of-arrival (TOA) differences measured at multiple spatially separated receivers. While effective, conventional implementations suffer from accuracy degradation when the source is located far from the receiver array, due to nonlinearities in the position estimation process.We adapt a method originally proposed for acoustic positioning, which offers a simple and robust approach to finding hyperbola intersections. Applied to radio-frequency signals, the method reduces computational complexity and mitigates sensitivity to measurement errors. Numerical simulations are performed to evaluate the influence of noise and receiver placement geometry on localization accuracy. The results demonstrate the method’s potential for operational use and provide a foundation for future experimental validation.
