Автономная навигационная система наземного транспорта на основе доплеровских датчиков для измерения векторной скорости
Abstract
The paper presents a method for signal processing of Doppler radio-wave sensors, which makes it possible to measure the vector of the ground speed of a land vehicle (cars, tractors, locomotives, etc.). The sensors are located along both sides of it and are directed at angles to the axis and to the underlying surface. It is shown how, based on the obtained data, it is possible to construct a real car route in a rectangular coordinate system. Special algorithms for signal processing are considered that allow to significantly increase the accuracy of determining the Doppler frequencies of the sensors, on which the accuracy of the calculation of the speed and the traveled distance depends.
