| Abstract | ||||
| In this paper a general analytical formula for the error induced in an angle tracking system by a phase front distorted jamming is derived. The electric fields originating from two coherent jamming sources are analyzed. The amplitude and phase of their resultant are computed; from which the parameters affecting that field are studied and the phase front equation is derived and plotted for different values of those parameters. Further analysis of the phase front equation leads to studying its inclination to the ideal spherical phase front, which leads to a general formula for the induced angular error. A similar approach was adopted in ref. [5] but the derivation was done in a special case. It is interesting that the resulting angular error depends only on the jamming system parameters and does not depend on the tracking system parameters or even on its type. | ||||
