Autonomous Navigation System of Ground Transport Based on Doppler Sensors for Measuring Vector Velocity

Resumo

A method for processing the signal of Doppler radio frequency sensors is given, which makes it possible to measure the ground speed vector of surface vehicles (cars, tractors, autocars, etc.). The possibility of constructing a real car route in a rectangular coordinate system is shown. Special algorithms for signal processing are considered which substantially increase the accuracy of determining the Doppler frequencies of the sensors.
