补充资料：导弹射击密集度
导弹射击密集度
missile firing dispersion
daodan sheli miiidu导弹射击密集度(missir。firing disper-sion)导弹炸点对散布中心的聚集程度。它与导弹射击准确度构成导弹命中精度。衡量射击密集度的尺度是炸点偏差的均方根偏差或方差。在导弹射击系统偏差很小时，导弹射击密集度近似反映导弹命中精度。在实际使用中，导弹射击密集度通常以圆概率偏差(CEP)或概率偏差表示。导弹射击密集度的大小取决于制导方法、导弹及其制导仪表的制造、射击诸元准备和操作，以及飞行中其他一些偶然因素干扰引起的随机偏差。为提高导弹射击密集度，需完善制导方法，提高导弹的制造精度、射击诸元准备和操作手操作的准确度，减少偶然因素的干扰，缩小各种随机偏差等。对射程较远的弹道导弹，在弹道主动段、中段和末段均进行制导，可使射击密集度(圆概率偏差)达几百米，几十米或更小。(康景良)
