FIELD: physics.
SUBSTANCE: adaptive radar set has a transceiving antenna, a transceiver, a Doppler frequency amplifier, an actuating cascade, first, second and third switches, a detector, a threshold device, a multivibrator, a storage device and a tuning unit, connected in a certain way. The tuning unit is designed for controlling the lower frequency limit of the Doppler frequency amplifier with shift towards higher frequencies.
EFFECT: more reliable detection of head-on low-altitude targets under noise conditions due to radio signals reflected from the surface of the target.
