Single-Position Location of a Radiation Source with a Curvilinear Motion and Allowance for Signal Period Evolution at the Reception Point

A single-position method of non-bearing passive location has been developed with allowance for the periodicity of a radiated pulsed radio signal during the motion of a radiation source along a curvilinear trajectory. The method does not require the current Doppler frequency to be estimated and the measured
parameter is the time discrepancy between the periods of the emitted and received signals caused by the motion of a source. The problems of the computational correctness and accuracy of the method are discussed and practical recommendations are made. A numerical example is given.
