Design and Experiment of Microwave Doppler Speed Radar for Agricultural Machinery Vehicles
摘要
Abstract
Speed measurement is very important for the accurate operation of agricultural machinery,at present,the ground wheel and GNSS method are mainly used.The ground wheel due to slippage leads to inaccurate speed measure-ment,GNSS needs differential positioning to improve the accuracy of speed measurement,the cost is high and difficult to popularize.To this end,an vehicle-mounted microwave Doppler speed radar based on FFT algorithm program was developed.The feasibility of the speed measurement system was determined by bench tests.Through field experiments,the accuracy of microwave Doppler radar and GNSS speed measurement was compared,and the results showed that the er-ror of the system under the conditions of true speed value of 3.4,6.6 and 9.7 km/h was±0.2 km/h,and the relative er-ror did not exceed 3%.The research results provided an important basis for the use of microwave Doppler radar speed measuring device in agricultural machinery operations.关键词
