摘要
传统水面舰艇雷达截面积(RCS)经验公式不能适用于毫米波。通过仿真方法模拟雷达电波的传播、散射机理,建立雷达工作的仿真模型并进行验证,然后在计算机上模拟各种条件,对水面舰艇的毫米波RCS进行仿真分析,并将大量仿真计算结果进行归纳总结,推导得出水面舰艇毫米波RCS的估算公式,实现RCS经验公式在Ka波段的外推使用。
Empirical formula for naval ships' radar cross sectional area (RCS) has been outdated and inapplicable for millimeter wave. By a simulation method, the model based on the scattering mechanism of radar electric wave was build and verified, then millimeter-wave RCS of naval ships based on different kinds of condition were imitated at calculator. After a great deal of simulation count outcome were sum up, estimate formulae for millimeter wave RCS of naval ships was derivative, and then the RCS empirical formula can be used for Ka-wave-band.
