系统接地问题是制约机动雷达机动性能的关键因素之一。通过对垂直地网、水平地网、复合地网三种机动地网技术的理论研究与测试验证,提出了不同地网技术接地电阻的近似计算方法,并在理论推导的基础上,提出了机动地网接地电阻的预估算法。经实际测试证明本文所提算法简单可行,并且已经在某型号机动雷达上开展了实际应用,能够为后续机动雷达应急接地提供重要的技术保障。

The key factor restricting the maneuverability of mobile radar is the system electrical grounding. By the theoretical research and actual verification of vertical grounding grid, horizontal grounding grid, and complex grounding grid, the approximate calculation method is proposed for electrical grounding resistance of different grounding grids. On the basis of theoretical derivation, the estimated algorithm for the mobile grounding network is proposed. The proposed algorithm is proved to be simple and feasible by the measurement results. The method has been applied to a certain type of mobile radar and provides important technical support for the fast deployment task of mobile radar.
