鐵翼雄風-
The concept of irradiance signal - to - noise ratio ( snr ) on the target plane and the minimum of the irradiance that can be detected by the detector was taken as the beginning, combined with a thorough analysis of the spectrum radiating feature of the target and the sky background, the atmosphere conditions, spectral filtering and the influence that the various components in the system have on the target irradiance on the detector ' s target plane and the background irradiance snr, the equation of the flying bomb ' s effect range affected by the point of burst measuring system is made, and all related factors that have an impact on the effect range are analyzed as well

On the basis of image segmentation, this thesis mainly discusses the algorithm of automatic target tracking in sequence images on the sea. firstly, in terms of the characteristics of image on the sea, such as weak contrast between target and background, borderline between sky and sea, spoondrift and so on, a method called barycenter tracking which is based on intra - frame information from the sequence images is proposed, in which the threshold method is the key algorithm
在圖象分割演算法研究的基礎上，本文重點從兩方面討論了海上序列圖象中運動目標的自動跟蹤演算法:首先，針對海上圖象的特點，即背景與目標間的弱對比度、存在海天線、魚鱗光和目標拖尾等，設計了以閾值分割為核心的基於幀內信息的形心跟蹤方法。 -
Secondly, other parameters such as temperature difference and emissivity of target and sky, molecular absorptive transmittance, instantaneous field of view ( ifov ), contrast threshold and radiant wavelength are discussed in detail
