Position Measure Method Researsh for Theodolite Using Radar Distance Data

In order to resolve the rapid positroning of the theodocite,improve using efficiency,giving to target position measurement method for theodolite using 2D radar distance data in a same station,combining pitch angle measurement dat-as of theodolite,conversioning radar measuring data to theodolite distance to target.Position error analysis indicate,when the position measured precision less than 5m,meeting position measured demand to target.The theodolite position measured does not need intersection measurement with other theodolites,which reducing the limit to the theodolites station.
