Passive location based on angular and power measurements of a system of radars

For system of radars implementing the triangulation location method, it is shown that a family of additional target range estimates can be constructed. These estimates are obtained by the combined use of angular and power measurements obtained by the radars. An analytical description of the operating zone of the triangulation system is given. The regions where this system gives incorrect results are determined. The results of the theoretical and experimental investigations demonstrate that the accuracy of estimates in these regions and the operational conditions of the system of radars is considerably improved.
