On the Application of Singular Value Decomposition and Tikhonov Regularization to Ill-Posed Problems in Hyperbolic Passive Location
Mathematical and computer modelling(2013)
摘要
Hyperbolic passive location of targets (e.g. used in the Multilateration systems for civil aviation) calls for the solution of highly non-linear systems. In this paper, we show how the effect of typical ill-conditioning of passive location, arising in many operational conditions, may be significantly mitigated by regularization techniques. The pertaining advantages with respect to the conventional (non-regularized) approach are shown in a realistic situation.
