Passive localization of emitter source using Inverse Diffraction Parabolic Equation

The localization of non-cooperative illuminators is a hot and difficult problem in the modern war. The arithmetic of Inverse Diffraction Parabolic Equation has a good applicability and stability characteristic for the passive localization in complex environment. Based on the localization method in the symmetrical atmosphere, the paper analyzed localization of single and couple illuminators on the conditions of standard atmosphere and terrain defilade, proposing the methods of data points selection and error ellipse protraction and having investigated the relationship between parameters and localization errors. Simulation analysis proved the characteristics of the algorithm. In the end, some parameters selection measure is presented to increase the accuracy of the localization algorithm and extend its application.
