What is the importance of line-of-sight in Pulse Radar measurements?

Line-of-sight is fundamental in Pulse Radar measurements as it ensures that the radar signals can travel directly from the radar system to the target and back without any obstructions. This direct pathway is crucial for accurate signal reflection because if barriers or objects obstruct the path, the radar may receive distorted or weak signals, leading to incorrect measurements of distance, speed, or target identification. The accuracy of the pulse echo returned to the radar is highly dependent on the unobstructed path; any interference can result in errors in data interpretation.

While enhancing range, speeding up data processing, or reducing energy consumption may be aspects considered in radar technology, they do not directly relate to the core necessity of maintaining a clear line-of-sight for achieving precise measurements in Pulse Radar systems.
