方位角
azimuth
fangweiiiao方位角(az imuth)从地面上某点的指北方向线起，顺时针方向至目标方向线之间的水平夹角。用度或密位表示。按指北方向线的不同，分为真方位角、坐标方位角、磁方位角等。军事上主要用于指示目标，现地判定方位，赋予火炮和导弹武器的射击方向，提供飞机、舰船的导航数据。真方位目二 方位角的种类角(A)，是以真子午线(真北)为基准方向，顺时针量到某一指定目标方向的水平夹角。由专门仪器用大地天文测量方法测定，也可用陀螺经纬仪直接测定，由0。一360“量度。坐标方位角(a)，是以高斯投影平面坐标网中的坐标纵线(坐标北)为基准方向，顺时针量到某一指定目标方向的夹角。可用经纬仪或方向盘测角进行推算，也可以由其他方位角换算，由OD一360“量度。磁方位角(M)，是以磁子午线(磁北)为基准方向，顺时针量到某一指定目标方向的夹角。用带磁针(罗盘、罗针)的测角仪器测定，由0o一3600量度。同一点的3个指北方向(真北、坐标北、磁北)，一般是不一致的。真北方向与坐标北方向之间的夹角，称为子午线收敛角(门)。真北方向与磁北方向之间的夹角，称为磁偏角(时。3种方位角在平面上的关系为:A~。+门，A=M+己。 (匀萃山)
