摘要
为了有效地获取再入段导弹的红外辐射特性,对其测量方法进行了研究。将不同时刻的目标距离和测量角作为已知量,利用非线性回归的方法估算目标运动参数,根据大气在高度85km以内的温度分布规律来估算由于气动加热后的目标蒙皮温度,进而分析迎头方向上的红外辐射特性。分析结果表明,反导系统红外探测器在再入飞行段的最佳工作波段是短波和中波。
An effective method for measuring infrared radiation of the tactical ballistic missile（TBM） in the reentry is presented. By regarding the range and the measurement angle of the target as the known quantity, according to the regularities of the temperature distribution of atmosphere within 85 kilometers in height, by estimating the motion parameters of the target using non-linear regression. the envelope temperature of the target by aerodynamic heating is obtained, and the infrared radiation characteristics of the target in the head-on direction is analyzed. The analysis results demonstrate that the infrared detector of the anti-missile system in the reentry can work well on short wave and medium wave.
