FIELD: transport engineering.
SUBSTANCE: invention can be used as sensor warning the driver of possibility of collision of automobile with obstacle in emergency. Proposed system to prevent collision of vehicles moving in column has antenna, modulator, two power amplifiers, mixer, frequency converter, detector, two speed recorders, distance recorder, dangerous distance calculator as to distance, running speed and approach speed, continuous-wave oscillator, summer, circulator, Doppler frequency filter, antenna position control circuit and two actuating circuits.
EFFECT: reduction of mutual interferences and provision of direct action onto moving automobile when distance between vehicles is dangerous.
