摘　　要：稀薄大气层外飞行的空间目标无国界限制,目前已成为对国土安全威胁最严重的一类重要目标,对该类目标的尺度精确测量特别是距离精确测量具有很强的实用价值。以地基雷达探测空间目标为背景,研究了游标法距离精确测量的原理,提出了解相位增量模糊的方法,仿真表明该方法是有效的。There are no national boundaries for space targets flying outer the thin atmosphere, which are regarded as the most important targets threatening to the territory safety. It＇s of powerful practical value to ob tain the accurate scale measurement of these targets, especially the range accurate measurement. Based on the background of space targets localization by ground-based radars,the principle of accurate range measurement based on venire method is studied, and the method of solving phase increment ambiguity is proposed. Simulations demonstrate the effectiveness of the above method.
