Emitter target recognition based on multi-sensor data fusion of ESM and IR

The method of emitter target recognition based on multi-sensor system of ESM and IR is discussed in this paper. First, based on the multi-feature measured by ESM system, a new method to calculate the BPAF (basic probability assignment function) with synthetic fuzzy evaluation is proposed. Based on the IR image, the method to calculate the BPAF with the gray correlation analysis is proposed too. And further, the paper introduces the multi-sensor data fusion method based on the D-S evidence theory, which is applied to the emitter target recognition of multi-sensor system of ESM and IR. The experiments show that the proposed method is practicable and effective.
