WebSpecifically, by transforming the inequality constraints into exponential functions, Lagrangian multipliers can be used to determine the source locations via Newton’s method. In addition, the constrained CRLB for source localization with distance and velocity correlation constraints is also derived. WebThe geolocation Cramer-Rao lower bound (CRLB) is derived and the performance improvement due to the use of target altitude information is quantified. An algebraic geolocation solution is developed and its approximate efficiency under small Gaussian noise is established analytically. Its sensitivity to the target altitude error is also studied. WebThe brightness function data is very weak, so we have to use a constrained CRLB on the shape parameters to form the con dence regions. Algorithms for reconstructing the shape of a convex object from multiple measurements of its brightness function were developed in [2] and [3]. The Cramer-Rao bound analysis presented here provides statistical ... josh bowlin attorney
