What should be avoided to minimize radar signal interference?

Minimizing radar signal interference is crucial for ensuring accurate readings and reliable performance. Obstructions that block the line of sight can severely impact the radar's ability to transmit and receive signals effectively. When there are physical barriers in the path of the radar waves, such as buildings, trees, or even terrain, the signals can be absorbed or reflected, resulting in weaker or distorted returns. This interference can lead to inaccurate data being collected, which in turn can affect decision-making processes and the efficacy of the radar system overall.

In contrast, while shorter radar waves, positioning devices too closely, and using older models may introduce variability in performance or efficiency, they do not inherently block the transmission path in the same direct way as physical obstructions do. Therefore, ensuring a clear line of sight is vital for maximizing the integrity of radar signal transmission and reception.
