	  abstract     = {One of the defects of stepped frequency radar systems
is their sensitivity to target motion. In such systems, target motion
causes range cell shift, false peaks, Signal to Noise Ratio (SNR)
reduction and range profile spreading because of power spectrum
interference of each range cell in adjacent range cells which induces
distortion in High Resolution Range Profile (HRRP) and disrupt target
recognition process. Thus Target Motion Parameters (TMPs) effects
compensation should be employed. In this paper, such a method
for estimating TMPs (velocity and acceleration) and consequently
eliminating or suppressing the unwanted effects on HRRP based on
entropy minimization has been proposed. This method is carried out
in two major steps: in the first step, a discrete search method has
been utilized over the whole acceleration-velocity lattice network, in a
specific interval seeking to find a less-accurate minimum point of the
entropy function. Then in the second step, a 1-D search over velocity
is done in locus of the minimum for several constant acceleration
lines, in order to enhance the accuracy of the minimum point found
in the first step. The provided simulation results demonstrate the
effectiveness of the proposed method.
