Abstract

The invention discloses an unmanned driving automobile obstacle-avoidance system based on a radio-frequency signal. The system comprises a radio-frequency receiving / transmitting system, an analog to digital converter, an FFT (Fast Fourier Transform) module, a modulus calculating circuit, a non-coherent integrator, a CFAR (Constant False Alarm Rate) detection circuit, an automatic obstacle-avoidance module and a driving control module. By virtue of the system, an unmanned driving automobile can be used for automatically avoiding obstacles and obstacle-avoidance manners are diversified; and a driving path can be automatically adjusted and a planned driving task is finished. The unmanned driving automobile obstacle-avoidance system is simple in structure and convenient to use and has relatively great practical value.

Description

technical field [0001] The invention relates to an automobile obstacle avoidance system, in particular to an unmanned automobile obstacle avoidance system based on radio frequency signals. Background technique [0002] In recent years, with the rapid development of the economy, the number of private cars is increasing day by day, which has caused road congestion and many traffic accidents, which have caused huge losses to people's personal and property. There are many reasons for causing traffic accidents, and the main factor is the driver's own reasons. Specifically, it is caused by the driver's failure to make correct predictions about the occurrence of the accident. If some measures can be taken to guide the driver's operation, the incidence of traffic accidents will be reduced. [0003] With the rapid development of the automobile industry and the continuous improvement of people's living standards, automobiles have replaced traditional means of transportation. As ther...
