Road Information Based Air/Ground Target Classification for Airborne Early Warning Radar

Air/ground target classification is a key step for ground target filtering in airborne early warning radar,which can improve the quality of target track effectively.On the basis of exploiting target track information and ground road information,a method for air/ground target classification based on similarity of track and road was proposed.First,a fast arithmetic matching target filtering plot to a section of road was given,which could choose the roads used to classify air targets and ground targets subsequently.Then,to the roads with winding,average distance and correlation coefficient between target track and road were calculated out.Finally,target classification was completed according to threshold decision and sliding window processing.The simulation results show that the method can implement air target and ground target classification accurately for different types of target track distribution.
