提出了一种将星图模拟技术应用于星空背景空间目标提取的方法，建立了地基光测设备的星图模拟模型，推导了光轴指向计算和星体到焦平面成像的坐标转换。利用模拟星图生成掩模，对实拍星图处理去除恒星背景。实验证明利用模拟星图能够有效去除恒星背景提取空间目标。
提齣瞭一種將星圖模擬技術應用于星空揹景空間目標提取的方法，建立瞭地基光測設備的星圖模擬模型，推導瞭光軸指嚮計算和星體到焦平麵成像的坐標轉換。利用模擬星圖生成掩模，對實拍星圖處理去除恆星揹景。實驗證明利用模擬星圖能夠有效去除恆星揹景提取空間目標。

A method for space target extraction in star background image based on star image simulation is put for-ward.The star image simulation model of optical measuring equipment based on the foundation was established.Opti-cal axis direction and coordinate transformation between stars and focal plane were calculated.Masks were generated by star image simulation,and background stars were removed for real star images.Experimental results show that the method can remove the background star and extract space target effectively.
