Motion modeling and wideband radar echo simulation for midcourse rolling target

Abstract:

The main differences between warhead and bait are their movement ways in the midcourse of ballistic missiles，and rolling motion is the major way for bait. The motion model was established based on physical，movement and scattering characteristics of midcourse rolling targets，and the mathematical expression of the wideband Linear Frequency Modulation(LFM) radar echo was deduced．Then wideband radar echoes were simulated and rolling period was estimated based on the changes of target radial length．The simulation results indicate that the wideband radar echoes of midcourse rolling targets have something to do with the target attitude motion parameters and the physique parameters，which will provide an important basis for midcourse target identification.
