基于雷达回波显影技术的雷达吸波材料涂覆方法研究

Study on Coating of Radar Absorbing Materials Based on Radar echo Development

  • 摘要: 为尽量控制涂覆雷达吸波材料对船舶带来的重心上移、成本提升以及维护保养工作量增加等负面影响,提出一种基于雷达回波特征显影技术确定船体及设备的重点涂覆区域的多目标优化设计策略。通过该方法对某船舶进行成像分析,利用本文提出的优化策略对船舶的雷达散射截面积(Radar Cross Section,RCS)和涂覆区域进行优化设计,得到相关的pareto和非pareto解集,并反演了工程应用场景。结果表明:该方法可较为准确的确定重点涂覆区域,仿真得到了至少10个pareto最优解(包括两极解),利用pareto解集对该船舶开展工程应用反演,在涂覆的面积比小于11%的条件下,RCS总平均值下降超过了53%。仿真验证了所提出方法的有效性,对船舶目标的RCS控制具有较好的工程应用价值。

     

    Abstract: In order to control the negative effects of the coating of radar absorbing materials on the ship, such as the shift of center of gravity, the increase of cost and the increase of maintenance workload, a multi-objective optimization design strategy based on radar echo feature development technology is proposed to determine the key coating area of the ship and equipment. This method is used for imaging analysis of a ship, and the Radar Cross Section (RCS) and coating area of the ship are optimized by using the optimization strategy proposed in this paper. The relevant pareto and non-pareto solution sets are obtained, and the engineering application scenarios are reversed. The results show that the proposed method can accurately determine the key coating area, and at least 10 pareto optimal solutions (including bipolar solutions) are obtained by simulation. Using pareto solution set to carry out engineering application inversion for the ship, the total average RCS decreases by more than 53% when the area ratio of coating is less than 11%. Simulation results show that the proposed method is effective and has good engineering application value for ship target RCS control.
