摘　　要：系统基于啁啾扩频超宽带技术,采用对称性双边与双路测距定位技术,降低噪声、干扰和多径效应,提高测距定位精度,对其测距定位算法进行优化。解决工作面现场的水平和垂直方向起伏弯曲而带来的超视距问题,能够具有方向识别能力。抗干扰性强,覆盖距离大。Based on chirp spread spectrum ultra-wideband technology, system adopts Symmetric Double-Sided Two Way Ranging technique （SDS-TWR for short） to reduce noise, interference and multi-path inference and im- prove accuracy of ranging and location. The location algorithm is optimized. The problem of beyond visual range caused by the fluctuation and bending in horizontal and vertical field is solved in mining face. System has anti-jam- ming capability and covers great distance.
