These radars, included in the MRK-411 multi-frequency radio engineering system, are the eyes and ears of the aircraft: Operators receive information in active and passive (without revealing their location) modes and can intercept the enemy's radio communications.
The main feature of the Tu-214R's radars is ground-penetrating radar (GPR) scanning.
In other words, the aircraft can see through the ground. Any objects hidden under the ground, covered with snow or sand, or disguised by trees, will be detected by the Tu-214R. It will take a radar snapshot and immediately transmit the information to the command post.
