摘　　要：无源时差定位的布站方式对作战区间的定位精度有直接影响。在三站时差定位精度模型的基础上,对直线布站和三角形布站下的定位精度进行了分析与仿真,得出了较为合理的布站方式。最后分析了两套设备协同定位较单套设备定位的优越性,并对两套设备协同定位时不同布站形式对定位精度的影响进行了讨论,提出了两套设备协同定位时应采取倾斜直线布站的方式,对于设备的实际作战运用具有一定应用价值。Disposition of passive TDOA location has a direct effect on location precision in war zone. Based on location precision model of three-station TDOA location, analysis, location precision of beeline and triangle disposition is discussed and simulated, and a rational disposition method is obtained. In the end, the advantage of optimizing disposition with two equipments compared with a single one and the effect of different disposition forms on location precision are studied. It is proved that the method of inclining beeline disposition with two equipments for cooperation is available for real battle application of equipment.
