FIELD: physics.
SUBSTANCE: radar station with space probing with phase-shift keyed signals includes a reception antenna, a high frequency amplifier, second and third mixers, first and second phase doublers, preamplifier, frequency tripler, video amplifier, low-pass filter, high-pass filter, audio frequency amplifier, headphones and a threshold unit, connected in a certain way.
EFFECT: getting rid of restrictions on detection range in the near zone, and possibility of detecting and continuous detection of radar signals reflected from fixed or low-speed ground targets owing to use of phase-shift keyed signals with linear adjustment of duration of partial radio pulses in the radar station.
