| 摘要: |
| 针对近程目标的机动特性以及在近距离询问信号饱和使应答机抑制等因素造成二次监视雷达不能稳定跟踪目标的现象，提出了一种新的跟踪方法，采用询问编排、功率控制等措施让应答机能有效应答，并通过近程跟踪滤波、航迹融合来实现对近程目标的稳定跟踪。该方法提高了系统的跟踪效能，近程目标的应答率提高到了80%左右，适合于二次监视雷达系统对近距离目标跟踪要求严苛的场合。该方法已在实际工程中成功应用。 |

| Abstract: |
| In view of the tracking problem caused by short-range maneuver flight target and transponder suppressed due to strong interrogation signal in secondary surveillance radar(SSR) system,a new tracking method is proposed.In the method,interrogation arrangement,power control and other measure are used to strigger transponder reply and realize stable tracking of short-range targets by short-range tracing filter and track fusion.The proposed method can improve the tracking system performance，the reply rate of short-range targets is improved to around 80%,and it is suitable for application in complex short-range target tracking with SSR system.The method has been successfully applied in an engineering project. |
