采用高频法分析舰船桅杆对总体RCS的影响

Analyzing the Influence of Ship Mast to Total RCS by High-frequency Method

对于舰船一类电特大尺寸复杂目标雷达散射截面(RCS)的计算通常都是采用高频法。分析桅杆天线对舰船总体RCS的影响,研究实际应用高频法预测分析舰船RCS特性的一些关键技术。结果表明,天线与天线之间存在的多次散射效应对舰船的总体RCS产生较大的影响。

For the complex and large targets like naval vessels, the computation for their RCS usually uses high-frequency approach. Presenting the geometry modeling and the computation principle on naval vessel's RCS, this paper puts the emphasis on the key techniques of computing the naval vessel's RCS based on high-Frequency approach with the analysis on mast's effect to the whole RCS as the example. The conclusion indicates that the Double Bouncing scattering among the antennas brings great effect to the vessel's total RCS.
