AWR1243BOOST: AWR1243 for Road traffic classification

Dear TI Team,

We have used your AWR1243 Boost Eval kit for traffic vehicles classification with RAW data extracted ,  we are successfully completed our testing and classification however classifications results are around 85% for most vehicles , two wheeler, Auto but the results for pedestrian were below 80% , in our application Radar is mounted on pole looking at ground will there be ground clutter which is reducing our signal quality and the accuracy of results ?, hence our mount is tilted and looking towards ground , emulating traffic sensor and trying to classify using machine learning algorithms ? 

Any feedback or comments will help us a lot ,

Thanks in Advance .
