In the context of radar meteorology, ( k^2 ) is related to the performance and characteristics of an antenna system. The correct calculation reflects the dependence of ( k^2 ) on parameters such as ( \alpha ) (which typically represents losses or gain), ( \beta ) (which often stands for directivity or another gain-related factor), and the frequency ( f ).

The second choice indicates that ( k^2 ) is proportional to both ( \alpha ) and ( \beta ), while also being influenced by the square of the frequency ( f^2 ). This is an important relationship because the frequency of operation plays a significant role in the behavior of radar waves, including how they propagate and interact with atmospheric phenomena.

In antenna theory, the gain and efficiency of an antenna system can often be expressed in a manner that incorporates quadratic relationships with frequency due to the physics governing electromagnetic wave propagation. As frequency increases, effects such as beamwidth and loss can change, thus affecting the antenna's performance parameters. Therefore, the formulation ( k^2 = \alpha \cdot \beta \cdot f^2 ) accurately reflects these complexities and relationships within the antenna system.
