The radar shroud is the first line of defense against which interference?

Explanation:
The key idea is shielding against electromagnetic interference. The radar shroud acts as the outer barrier around the antenna, reducing stray RF energy from entering the radar system. By limiting external noise at the front end, it helps preserve the integrity of the received signal before more advanced processing or filtering is applied. Weather and lightning are environmental factors that require separate protections, and radar jamming is deliberate interference addressed by other defensive measures. EMI is the constant, pervasive type of interference the shroud is designed to blunt as the first line of defense.
