Embodiment Construction
[0033] The signal model of the moving target track in the radar image is as follows: figure 2 shown. Among them, ● represents the center of mass of the moving target; v r , v α 、α r 、α α Respectively represent the radial movement velocity, azimuth velocity, radial acceleration and azimuth acceleration of the moving target; R 0 Represents the slant distance between the target and the radar at time t=0, R t Represents the instantaneous slant distance between the target and the radar at time t, and its expression is:
[0034] R t = ( R 0 - ( v r t + a r t 2 / ...
