| Abstract: | Radar identical frequency jamming problem is an important problem restricting shipborne radars using.In order to solve the problem about identical frequency jamming between coherent-radars for the warship formation,aiming at the main characteristics of coherent-radars,difficulties of eliminate identical frequency jamming between shipborne coherent-radars are analyzed first.Then technical indexes are established based on correlation algorithm during multi-pulse in time domain.Finally a design method to eliminate identical frequency jamming between shipborne coherent-radars is proposed including timer modules,multi-pulse coherent module,MTI module and terminal handling module.Experiments on the sea show that this method can effectively eliminate identical frequency jamming between coherent-radars for the warship formation. |
