Abstract :
A novel algorithm for mitigating multipath effect of low elevation for passive monopulse radar based on the fractional Fourier transform (FRFT) is proposed with constructing the multipath model in this paper. Reflection LFM signal filtered and mitigated in FRFT domain. The statistical analysis is also performed which perfects the method theoretically, simulation results are provided to show the validity of our method.
