Propagator methods for finding wideband source parameters

摘要: Abstract In this paper, an investigation of the passive angular location sources using array sensors is presented. First, propagator method, which algebraic and linear operator extracted from cross-spectral matrix received data, extended to wideband signals through transformation matrices. This development reduces rather expensive eigendecomposition matrices at each frequency analysis bandwidth used in well known eigenstructure high-resolution methods. Then, presence white noise with different powers along array, a new partitioned method developed improves localisation sources. improvement based on particular choice partition corresponding propagation operator. The also estimate antenna shape signals. It known, narrowband case, that interest knowing illustrated by signal ratio directivity. results simulations are provided illustrate theoretical predictions.
