Single-Position Passive Location of a Moving Target with Consideration of the Evolutionof the Period and Level of the Pulsed Radio Signal

The single-position hybrid method for bearing-free passive location of a moving source of pulsed periodic radio signal emission with consideration of temporal and energy measurements of a stationary observer is proposed. The method is applicable for any directions of target motions for both straight and curved trajectories; no current estimation of the Doppler frequency is required; the measured parameters are the time shift and relative power conditioned by the evolution of the signal period and level at the observation point. The issues related to investigation of the character of the time shift evolution, construction of algorithms of determining the range and other parameters of motion, computational correctness and accuracy characteristics of these algorithms are considered. Practical recommendations and a numerical example are provided.
