What is the purpose of adding an additional ground according to ground conditions?

The purpose of adding an additional ground according to ground conditions is primarily to supplement the Surface Wave Guidance System (SWGS). By introducing supplementary ground elements based on specific terrain and environmental factors, the effectiveness of the SWGS can be enhanced. This is crucial in areas where standard configurations may not suffice due to unique geographic or atmospheric considerations, ensuring that the system can function optimally in providing guidance and support for air defense operations.

This addition is particularly important in environments where communication signals might be interfered with, or where traditional coverage might not reach certain critical areas. Thus, the supporting structures not only improve the SWGS but also contribute to maintaining a robust and reliable operational capability in air defense scenarios.
