In radar terminology, what does "HITS" typically indicate in relation to altitude?

In radar terminology, "HITS" refers to a context where it indicates approximate altitude. This term is often associated with radar systems that provide altitude data as part of their operational capabilities. When radar systems detect a target, they can calculate and display its altitude, allowing operators to understand the vertical position of the target in relation to their own platform or ground level.

The use of "HITS" in this context signifies that the data being presented is an approximation rather than an exact measurement, which is crucial for operators to maintain situational awareness. Understanding these approximate altitudes helps in various applications, such as air traffic control, military operations, or search and rescue missions, where knowing the altitude of detected objects can be vital for decision-making and safety.

The other options relate to different aspects of radar functionality. Specific weapon effectiveness focuses on the performance of weapon systems, momentary radar return pertains to transient signals received by the radar that do not provide altitude information, and enemy aircraft detection is more about identifying and assessing threats rather than their precise altitude. Each of these is important but does not specifically define what "HITS" indicates in relation to altitude.
