T1 REDUCTION OF ASPECT DEPENDENT SPECKLE FLUCTUATIONS IN HIGH-RESOLUTION RADAR RANGE PROFILES JF Telecommunications and Radio Engineering JO TRE YR 2010 FD 2010-06-16 VO 69 IS 8 SP 687 OP 698 K1 high-resolution range profile K1 automatic target recognition K1 speckle K1 bispectral estimation K1 aircraft AB This paper deals with the analysis of the variability of high-resolution radar range profiles caused by the changes of aerial target aspect angle regarding to the radar line of sight. An approach based on radar range profiles reconstruction from the averaging of sets of short-time bispectrum estimates is developed and investigated. Results of computer simulations obtained for aerial targets of different types demonstrate that the sensibility of range profile estimates with respect to the target aspect angle changes decreases when the proposed bispectrum-based estimation is used.
