A TDOA, when multiplied by the propagation speed, is the difference in the true ranges between the 'vehicle' and the two stations involved (i.e., the unknown TOT cancels). Systems have been developed for both TOT and TDOA algorithms. In this article, TDOA or hyperbolic systems are addressed first, as they were implemented first. TDOA performs well for new and emerging signals with complex modulations, wide bandwidths, and short durations. AOA typically performs well on narrow-band signals, but advanced AOA methods can be applied for locating any signals including wideband, complex, and short duration. TDOA performance is a strong function of signal bandwidth. 2014-03-04 · TDOA (Time Difference Of Arrival) Directional Antenna.

In localising an emitter, non-line-of-sight errors are added if an obstacle U-TDOA is uplink method similar to downlink OTDOA.

### UWB-lokaliseringstekniker — TOF och TDOA - Woxu Wireless

本发明涉及一种tdoa和tof混合的定位方法，其特征在于，包括：步骤一：服务器选取主基站和从基站并完成基站间时间同步 arrival(TDOA/FDOA) joint localisation algorithm [22,23]and the sensor position uncertain localisation algorithm [24,25]. A multi-input and multi-output passive radar joint localisa-tion algorithm based on TDOA/AOA was proposed in [26]. It has good localisation performance on the z-axis, but the localisation accuracy in the ﬁrst stage is not high. The algorithm partitions the signal received with the same receiver into multiple non-overlapping short-time signal segments, and then uses the TDOA, the FDOA (TOA) and time difference of arrival (TDOA) based methods, no synchronization is required between a target node and any anchor node, nor is required among TCI TDOA Systems.
