What effect does the elevation of a radar platform have on detection range?

The elevation of a radar platform significantly influences its detection range due to the improved line-of-sight it provides. When a radar system is higher in elevation, it can cover a wider area and detect objects that are farther away. This is because radar waves can propagate further without being obstructed by terrain features such as mountains, buildings, or foliage.

Higher elevation reduces the impact of obstacles that would otherwise block the radar signals, enhancing the ability to detect both high-altitude and low-altitude targets. This improved line-of-sight allows radar systems to scan a larger volume of airspace, thereby increasing overall detection capability. In operational contexts, such as surveillance and defense, this increased range is crucial for early warning and threat assessment.

The other choices do not reflect the reality of radar detection mechanisms related to elevation, highlighting the unique advantages provided by a higher vantage point.
