What is the primary benefit of higher antenna gain in Pulse Radar?

The primary benefit of higher antenna gain in Pulse Radar is that it improves the ability to detect weak signals. Higher antenna gain means that the radar can focus more of its transmitted energy in a specific direction, resulting in a stronger signal being reflected back from targets that are far away or have a small radar cross-section. This increased sensitivity allows the radar to pick up weaker signals that might otherwise go undetected, which is crucial for identifying distant or stealthy objects.

While the increase in radar range and sensitivity to weak signals are related, the focus here is on the ability to discern and detect those weaker echoes that may be crucial for target identification in various operational scenarios. Higher antenna gain does not inherently enhance processing speed or reduce the size of radar equipment, as those aspects are more influenced by other design parameters and technologies used in the radar system.
