Abstract

Time Difference of Arrival (TDOA) based measurements are used for passive localization systems in various applications. While significant research has been performed on the development of TDOA measurement-based approaches, there has been relatively little focus on the sensor deployment geometry which significantly impacts the location estimation accuracy. Therefore, a study on the effects of four sensors’ placement on location accuracy has been conducted. Several factors are considered in numerical simulations analysis which have an obvious effect on the localization accuracy. Based on the analysis of the Geometric Dilution of Precision (GDOP) performance metric, a comparison is conducted between square and star geometries. The results show that the star geometry gives better performance in terms of location estimation accuracy, especially when the main receiver is positioned within the polygon formed with baseline angles of 120°. Furthermore, the star geometry is used to study also the influence of sensor height and baseline length to achieve an optimum three-dimensional sensor placement with four sensors. The results can be applied to enhance the sensor deployment in 3D sensor geometry for TDOA-based localization systems.
