| 英文摘要: |
| Due to electronic jamming transmitted by hostile electronic jamming equipments and unintentional jamming from other illuminating sources in the complex electromagnetic environment, the performance of non-cooperative passive detection systems may degrade it significantly. To solve the problem, a receiving frame with multiple channels for signal preprocessing is designed and a theoretical analysis to the received signals in the complex electromagnetic environment is provided. Furthermore, a scheme for jamming removal using independent component analysis is proposed. Simulation results demonstrate the proposed scheme appears as a very appealing solution for removal of jamming and an approximate 10dB signal to distortion ratio over traditional schemes is obtained. |
