同的定位法和定位算法，就能形成多种不同的定位跟踪方案。(The passive location and tracking technology is essentially the fusion of location tracking method and location tracking algorithm. Location method and location algorithm are the core of passive location technology, they determine the positioning accuracy and real-time performance of the system. Combined with different positioning methods and positioning algorithms, a variety of different positioning and tracking schemes can be formed.)
