Radar ECCM Performance Indexes Analysis and Testing Platform Design

The radar ECCM performance using outfield experiment would be accompanied by high system complexity and cost in complex electromagnetic environment.After analyzing the electromagnetic environment and relative evaluation index,the DSP chip and ARM display control terminals（DACT） are applied to design the radar ECM performance testing system with consideration of radar ECM cases.The jamming styles and parameters can be smartly intercalated.The rubs are resolved such as radar states data acquisition,echo real time simulation and radar environment DACT setup.Then a radar ECM semi-physical simulation experiment is examined in the tactical environment generated by the testing system.Experiment and data processing results show the measuring method are valid and practical.The method can be used to solve problems such as radar ECCM performance evaluation and radar advanced design a when the equipment is relatively small.
