Multipath effects compensation for radars or seekers based on multicarrier techniques

For multipath effects compensation in complicated hedge-hop circumstances, methodologies based on orthogonal frequency-division multiplexing (OFDM) radar signal are proposed to get target tracking information extracting equation set in this paper, after hedge-hop multipath model presentation and hedge-hop circumstances influence analysis on seeker guidance radar error output. By comparison with traditional multipath analysis and compensation method, the proposed approach can get target direction accurately at one sensing period without the limitation of relative velocity and position between target and radar(seeker). Sample Simulation result is also presented to verify the effectiveness of the proposed approach.
