Abstract:
To solve the measurement problems of differential delay and differential frequency offset in dual-station passive location system,the algorithm and feasibility of the joint estimation of the differential delay and differential frequency offset is studied using the cross ambiguity function.The estimation standard deviation expressions for the differential delay and differential frequency offset of common radar signals are analyzed and derived.The joint estimation simulation result and realization method of differential delay and differential frequency offset of typical radar signals are also presented.Parallel processing and search range reduction are used and the calculation time of ambiguity functions is improved.
