SMALL-SIZED RADAR OF MOTOR VEHICLE Russian patent published in 1998 - IPC

FIELD: radiolocation, safety of traffic. SUBSTANCE: invention refers to radiolocation means and this small-sized radar is designed for installation on motor vehicles to keep safe distances and speed in traffic and to prevent collisions by warning driver of approach to obstacle or mobile object in route. It includes transceiver high-frequency part, pulse generator, preamplifier, bandpass amplifier, filter analyzer of spectrum, code generator, adder, heterodyne frequency synthesizer, sound reproduction unit and control desk, secondary power supply source and reference voltage source connected in series. In contrast to known analogs this radar is inserted with rejection filter, two-pole limiter, former of synchropulses, synthesizer of pulse trains, integrator, demultiplexer, amplitude discriminator, multiplexer, key, delay unit, code fixation unit and synthesizer of signal of audio frequencies connected to sound reproduction unit connected in series and selector of code change and pulse stretcher connected to controlling input of key also connected in series. EFFECT: diminished size and mass characteristics, increased functional reliability and safety of motor vehicle running. 8 dwg
