This paper focuses on the problem of source localization using time-difference-of-arrival (TDOA) measurements in both 2-D and 3-D spaces. Different from existing studies where the variance of TDOA measurement noises is assumed to be independent of the associated source-to-sensor distances, we consider the more realistic model where the variance is a function of the source-to-sensor distances, which...
The relative equations between interceptor and target are conducted in rotation coordinate of Line of Sight. An error propagate model of LOS rate is established which is based on CADET (Covariance Analysis Describing Function Technique). This model takes several factors into consideration, such as estimate error of LOS rate, acceleration saturation of interceptor, sampling rate. A set of analytical...
In this paper, we consider the problem of locating an Automated Guided Vehicle (AGV) which moves on a plane in an industrial environment by means of Ultra-Wide Band (UWB) signaling from fixed Anchors Nodes (ANs) situated in the (three-dimensional) space. An analytical approach to optimize, under proper (realistic) constraints, the placement of the ANs used to locate the AGV is proposed. Analytical...
