摘要
针对低空飞行武器目标背景复杂、干扰严重,导致外测设备难以稳定跟踪、可靠定位的困难,提出了基于多站遥测数据的时差定位方法。该方法利用无线电信号传输时不同距离的时差原理,通过提取多个位置遥测站同帧数据时间差实现对武器目标的定位,并进行了平面定位测试和三维空间武器实弹测试。仿真与试验结果表明,定位精度满足测控设备跟踪引导目标的精度要求,技术可行,方法合理。
Because of the complex background and serious interference of the low-altitude flying weapon,it is difficult to track stability and locate reliably by the Range Tracking equipment.Based on the principle of the time difference of arrival (TDOA) on wireless signal transmission,the method of TDOA Location based on Telemetering Data of Multistation is proposed.The land test and three dimensions space weapon test is proceeded,the results indicated that the positioning accuracy can meet the requirements of tracking,and the method is reasonable and feasible.
