Which RADAR Electronic Protection (EP) technique helps prevent a RADAR receiver from being saturated by jamming?

Instantaneous Automatic Gain Control (IAGC) is designed specifically to manage the gain of a radar receiver dynamically, which helps prevent saturation due to strong jamming signals. By adjusting the gain in real time based on the incoming signal levels, IAGC ensures that valid radar returns can still be detected even in the presence of overwhelming jamming. This is critical in maintaining the effectiveness of radar operations, as it allows for the differentiation between legitimate targets and jamming interference.

In contrast, other techniques may focus on different aspects of radar performance or address jamming in alternative ways. For instance, Lobe On Receive Only (LORO) deals primarily with the directional characteristics of radar reception but does not directly manage signal levels to counteract saturation from jamming. Moving Target Indicator (MTI) is used to distinguish moving objects from stationary background clutter, thereby enhancing target detection, but it does not involve gain control mechanisms. Non-Synchronous Pulse Suppression (NSPS) focuses on mitigating specific types of jamming by suppressing non-coherent jamming signals but does not provide the continuous gain management that IAGC offers.

Therefore, the effectiveness of IAGC in dynamically adjusting the radar receiver's sensitivity is what makes it the appropriate choice for
