| 摘 要： | 在分析了低RCS目标外形优化中现有的两种目标函数的局限性的基础上，根据雷达检测概率与目标RCS分布之间的关系，提出了一种新的目标函数，即目标在威胁区域内其RCS大于规定的临界RCS的概率。算例表明本文所提出的目标函数比现有的目标函数更为有效，适用范围更广。为低RCS目标外形优化设计以及气动与隐身一体化设计提供了一个合理而有效的目标函数。

| Abstract: | Two objective functions used currently for optimum design of low radar cross section(RCS) aircraft are analysed and their shortcomings are pointed out. A new objective, that is, the probability that the RCS of the target in the sector of radar threat exceeds the critical RCS, is proposed based on the relationship between the probability of radar detection and RCS distribution. An example is presented to illustrate that the new objective function proposed by the paper is very useful and effective for optimum design of low RCS aircraft configuration, as well as for the integrated design of aerodynamic and low observable disciplines. |
