| 针对相控阵体制航管二次雷达系统在雷达近程探测空域内无法稳定监视目标的问题，提出了一种提高航管二次雷达系统对近程目标跟踪稳定性的方法。基于现有航管二次雷达系统的硬件架构，设计了在对监视空域进行航管扫描询问过程中密集插入对近程目标跟踪询问的工作方式，并给出了航管近程跟踪询问流程和波位随机同步跳转控制时序的详细设计方法以及对航管近程跟踪能力的估算方法。仿真计算结果验证了该方法的可行性和有效性。 |

| Abstract: |
| For the problem that short-range targets are unable to be surveilled stably by secondary surveillance radar(SSR) system based on phased array antenna(PAA),a method is proposed to improve the SSR system's stability of tracking short-range targets. Based on the hardware architecture of the existing SSR system,a new operation mode is designed to insert short-range tracking interrogations intensively in the process of SSR scan interrogation. The flow of short-range tracking interrogation and the time sequence design of beam position jumping synchronously are presented，and an estimation method of the capability to track short-range targets is also introduced. Simulation result validates the feasibility and effectiveness of the proposed method. |
