multipleshooting to find the roots of the non-linear functions

一种（LFM）Linear frequency modulation雷达的仿真-Linear frequency modulation (LFM) radar simulation

手机上计算公路平面线型中、边桩坐标，或坐标反算为中边桩，带上手机就可在野外查询。-Calculating linear plane on the phone in the road, while the pile coordinates, or coordinate inverse calculation of the pile side, you can take your phone in the field queries.

可以把公路整条线型参数输入手机中并保存，在野外作业时查询坐标数据。-You can put the entire highway linear parameter input your phone and save the query coordinate data in field operations.
