Abstract:In the past few decades, the Time Difference of Arrival location technology in distributed high‐frequency surface wave radar has attracted wide attention due to its simple system, low cost, and higher positioning accuracy. Based on the time difference direction‐finding algorithm, this article presents new mathematical expressions of geometric dilution of precision in the Time Difference of Arrival positioning systems. The time difference direction‐finding reveals that the angle measurements are accurate for an… Show more
