Gesture Sensitivity Analysis for High Range Resolution Profile of Midcourse Target

High Range Resolution Profile(HRRP)is easily to obtain,and can prov ide geometric structure information of the target,it has important applications in missile target recognition.For analyzing the gesture sensitivity of HRRP,t he two-dimensional scattering center of missile target distribution based on IS AR is extracted,and then the distribution of scattering centers in each posture in the range resolution cells is analyzed specifically.After that,the phase re lationship between the various scattering centers is calculated when the HRRP is in mutation,and at last combining with HRRP mathematical model,the cause of t he mutation is analyzed.The analysis result show that the interference between the scattering centers within the range resolut ion unit leads to HRRP attitude sensitivity.The specific impact of the scatteri ng centers within the range resolution unit on HRRP is analyzed through the expe riment.
