description The invention relates to a short-wave remote radiation source one-step locating method based on wide-area distributed single-antenna receiving. The method comprises the steps: building a mathematic model of an arrival signal relative to a short-wave remote radiation source position function based on the short-wave antenna signal propagation principle; converting the wide-area distributed single-antenna received data into frequency domain data based on the technology of Fourier transform, and building a mathematic function model of the short-wave remote radiation source position and the heightof an ionized layer through an initial measured value of the height of the ionized layer and the maximum likelihood estimation criteria; finally obtaining the short-wave remote radiation source position information in a one-step mode based on the particle filtering or iteration optimization algorithms. According to the invention, there is no need of a large-scale array receiving station, and the method can achieve the hig
