摘要
介绍了空中运动目标定位测量的经纬定位仪单站定向和双站异面交会定位原理,并对影响定向和定位结果的各个因素进行了误差分析和仿真。结果表明,交会角在[40°,165°]时,测量精度有明显地改善,为组网测量布站提供了依据,黑火药爆炸试验测量结果验证了该方法的可行性和测量精度。
The mothod used for obtaining a direction and a non-uniplanar intersection location of a moving airborne target via orientation theodolite is presented.The factor affecting the direction and location precision is made error analyzing and simulated.The result shows that the measure accuracy can be obviously improved when the intersection angle is between 40° and 165°,which provides a basis for the layout of the netted orientation theodolites.The measure result of some weapon testing demonstrates the method＇s feasibility and measure accuracy.
