Radar Signal Processing for Automated Vehicle Driving in Highway Scenarios
Multipath interference generated between radars operating in a traffic road environment can lead to false targets on radars.To this end,the following research is carried out to solve the problem of multipath interference of radar signals.Firstly,the multipath interference generated by the adjacent vehicle radar system is discussed,and it is characterized as a dynamic stochastic process.To validate the entire processing pipeline,simulation experiments are conducted utilizing MATLAB software,with particular emphasis on the simulation of the ranging,velocity and angle measurement algorithms.Through the comparative analysis of data,this paper estimates the performance metrics of radar.Subsequently,it establishes a highway model,constructs a radar model,and defines specific parameters at the same time.By utilizing signal processing functions,the velocity,distance,and azimuth information of the target vehicles are derived.Finally,the research results are visually displayed through drawing an aerial view of the radar vehicle.
