摘要
以高超声速乘波体为例,针对稀薄大气空间高超声速目标的红外可探测性能进行分析研究。采用工程算法计算了不同飞行条件下的飞行器驻点热流分布,由此得到其辐射平衡温度;采用小区间求和方法计算大气对红外辐射的传输衰减作用;考虑了目标与背景辐射强度差异、点目标成像的弥散现象对探测器作用距离的影响,建立了新的红外探测系统作用距离计算模型。仿真实验表明,弥散系数随着目标探测器间距离而变化;随着飞行器飞行速度的增加,系统对目标的探测距离增大,同时与长波波段相比,中短波波段时的探测距离更大。外场试验结果表明,与现有算法相比,本文方法具有较高精度。
Abstract
Taking hypersonic waverider for example, the infrared detectability of hypersonic object in rarefied atmosphere space is researched. Heat flux distribution of the stagnation point as well as radiation-equilibrium temperature is calculated under different flying conditions with engineering algorithms; then atmospheric transmittance is calculated by summation over small intervals. After considering both effects of radiation difference between object and background, and dispersion on detector′ s operating range, a new model for calculation operating range of infrared detedion system is built. By simulation, dispersion coefficient has varied with distance between object and detector; meanwhile, the higher the velocity of object is, the further the operating range is. When compared with long-wave spectrum, detector working at short-medium spectrum has better operating range. By field test, proposed algorithm has high accuracy when compared with existing models.
