假目标外形尺寸仿真精度的量化分析

为了合理地确定假目标外形尺寸仿真精度，分析了影响卫星光学相机极限分辨率的因素以及考虑大气影响下的假目标与背景的亮度对比对于卫星照相系统实际地面分辨率的影响。通过计算得到了卫星光学照相的实际分辨能力，确定了卫星光学照相条件下的假目标外形尺寸仿真精度要求，得出了假目标外形尺寸仿真精度可以控制在0．2m以下的结论。

Quantitative analysis of imitation precision of outline size for decoy

In order to determine the imitation precision of the outline size of decoy, some factors are analyzed which affect the utmost resolving power of the optical camera of the secondary satellite. The influences on the actual ground resolving power of the photograph system of the secondary satellite, which are acted by atmosphere and luminance contrast between decoy and background, are analyzed. The active resolving power under the optical photograph of the secondary satellite is obtained by calculation. The imitation precision request of the outline size of decoy under the optical photograph of the secondary satellitel is determined. The conclusion that the outline size of decoy can be controlled under 0. 2 m is reached.
