Abstract
A single-position hybrid method of bearing-free passive location of a moving source of pulsed periodic radio signal emission is proposed. The method takes into account temporal and energy measurements. The method is valid for all directions of target motion along both straight-line and curvilinear trajectories. No current estimation of the Doppler frequency is required; the time shift and relative power generated by the period evolution and signal level at the observation point serve as measured parameters. Issues related to determining the range and other parameters of motion, computational correctness, and accuracy characteristics are considered. Practical considerations and a numerical example are provided.
