Abstract:

Target recognition is the core difficulty in ballistic missile defense systems, this paper studies the polarization recognition problem of passive decoy during break through process of the ballistic missile. Firstly, based on a host of narrow and wide band polarization characteristics, and combined with data derived from anechoic chamber measurement, this paper performs polarization characteristic extraction and filtration, and removes redundant polarization characteristics. A synthetic recognition method based on narrow and wide band polarization characteristics for ballistic targets is proposed, and data derived from anechoic chamber measurement is used for validation. The result shows that the synthetic recognition method has better recognition performance than recognition method based only on narrow or wide band polarization characteristics.
