Spatial resolution of the passive location based on fourth-order correlation processing

The formation and specific features of the spatial resolution of passive lo cation are considered. The difference between the longitudinal and transver se resolutions achieved with the receivers arranged in a single plane is ex plained on geometrical grounds. Results of an experimental study of the spa tial resolution of the correlation location are presented. The results are found to be in a quantitative agreement with the theoretical predictions. T he experimental point-spread function closely approaches the function obtai ned from mathematical simulations.
