(一)前言在火控系统中,座标系的相互转换,是经常遇到的事。特别是几种常用座标系(现在直角座标、未来直角座标、现在球座标、现在柱座标、未来柱座标、弹道座标)经常根据不同的需要进行相互转换,诸如,目标的现在座标一般用球座标来表示;而目标运动参数则用直角座标或柱座标表示; (A) Preface In the fire control system, coordinate system conversion, is often encountered. In particular, several commonly used coordinate systems (now Cartesian coordinates, future Cartesian coordinates, now spherical coordinates, present cylindrical coordinates, future cylindrical coordinates, ballistic coordinates) are often transformed according to different needs, such as the target The coordinates of the general use of ball coordinates to represent; and the target motion parameters with rectangular coordinates or cylindrical coordinates that;
