Abstract

1,163,922. Measuring speed by radio and sound waves. SANGAMO WESTON Ltd. 3 March, 1967 [3 March, 1966], No. 9444/66. Heading H4D. In a system for providing a warning on each of several vehicles moving along a defined way (e.g. a road) of its approach to another vehicle, each vehicle transmits a rearward beam of radio or sound waves on a predetermined frequency, waves from the forward direction are received, and a Doppler beat signal is derived to effect the warning. In an embodiment centimetre waves are utilized and an audible warning is given. The transmitted energy may be pulse or amplitude modulated. When sound waves are employed, a filter rejects road noise. The modulation may be coded to identify different classes of vehicles. Obstructions, e.g. bridges, are provided with a transmitter radiating towards oncoming traffic. The warning signal may be visual. Beat signal amplitude indicates distance between vehicles.
