摘要
研究了无源定位方法,以及单目标无源定位技术。设计了城市中运动目标无源定位仿真系统,绘制了城市中无源定位仿真系统流程图,并编制了有关程序。该无源定位仿真系统的特点是硬件设备少,造价低;信号传送点到点收发,受电磁波泄漏干扰的影响大为减少,不易造成误码,提高了工作的可靠性,相对于有源定位技术该系统的抗干扰能力较强;由于采用了牛顿迭代法,有效修正计算误差,所以定位精度高;能够满足各种运动目标的监控要求,整个系统具有较高的性能价格比,尤其适用于民用,具有广阔的应用前景。
A method of passive location and passive location technology for single object is studied. A passive location emulation system for the moving objects in city is designed. And the flow chart for the passive system in city is designed and the program is compiled. The system features the less hardware, low costs, spot to sport signal transmission, high anti-jam ability to the electromagnetic leakage, less -miscoding, and high reliability, more satisfied anti - jam ability than active system. Because it uses Newton iterative method the system can effectively amend calculation errors with high location precision. It can meet the requirements of monitoring variety of moving objects, the system has high cost effectiveness and can be wildly used.
