| 摘 要： | 隐身技术是提高巡航导弹突防能力的重要技术手段，为分析外形隐身对巡航导弹电磁散射特性影响，建立了隐身、常规巡航导弹电磁模型，基于物理光学法和RCS减缩值，研究了外形隐身RCS曲线分布影响、频率响应特性、俯仰角响应特性。结果表明，外形隐身可大幅降低前后向散射特性，改变RCS散射波峰位置，使前后向曲线向内收敛；频率增加，前向均值和减缩值分别在-32 dBsm、25 dB左右振荡变化，其他角域RCS均值降低而减缩值增加；俯仰角变化较小时不影响散射特性，各角域RCS均值和减缩值呈振荡趋势，前向减缩值约为35 dB左右，后向俯仰角0度时最大。

| Abstract: | Stealth technology is an important technical means to improve the penetration capability of cruise missiles. In order to analyze the influence of shaping stealth on the electromagnetic scattering characteristics of cruise missiles, the electromagnetic models of stealth and conventional cruise missiles were established, and the distribution of RCS curves for shaping stealth, frequency and pitch angle response characteristics were studied based on Physical Optics method and RCS reduction value. The results show that shaping stealth could greatly reduce scattering characteristics in nose and rear direction, it also could change the peak position of RCS scattering and make the curve converge inward in nose and rear direction. And with the frequency increasing, the mean values and reduction values oscillate respectively around -32 dBsm and 25 dB, the RCS mean values decrease and reduction values increase in the other angular domains. While the scattering characteristics is not affected with small variation of pitch angle, and the RCS mean values and reduction values in every angular domains oscillate, the reduction mean in nose direction is about 35 dB, and the maximum value exists in the pitch angle of 0 degrees. |
