| 摘 要： | 基于调频广播的单站无源定位系统实际相当于收发分置的双基雷达,以调频广播的发射机作为辐射源,接收雷达位于另一处。在实际的无源雷达系统中,利用数字波束形成技术和比幅测角,可以得到目标方位角。再利用信号到达时间差,可以得到目标和雷达站间的距离信息,从而实现了固定单站对二维运动辐射源的无源定位。最后还给出了定位精度的计算机仿真结果。此定位方法在工程中取得了较好的效果。 |

| Abstract: | The monostatic passive location system is actually a bistatic radar system which employs a FM broadcast transmitter as the illuminator,and its radar receiver is located on another place.In the practical radar system based on external illuminator,the azimuth angle can be acquired using digital beam formation technique and the angle measuration by comparing amplitude.According to Time Difference of Arrival(TDOA),the distance between the target and the radar station is achievable.Thus an applicable passive location algorithm of moving target based on single fixed-site illuminator is available.Finally,the computer simulation results are presented,and good results has been achieved in engineering by this method. |
| Keywords: | bistatic radar passive location measuring angle by comparing amplitude ranging GDOP |
