An Approach of Search the Ambiguities of Carrier Phase in Multi-Observers Passive Location

摘要

Passive location technology has promising future in locating targets. This paper presents a new approach of search the ambiguities of carrier phase in multiobservers passive location. When the carrier exists in a target's emission signal, the accuracy of this location method can reach carrier wavelength level. The ambiguities are obtained by using the optimal searching method based on the theories of strain gradient. Clear theoretical analysis and example showed that this method is an effective way for multi-observers passive location.
