A new air target parameters estimation under jamming and clutter effect based on SOKT/IFrRT in airborne radar

The airborne radar is used mainly to detect the ground moving targets, but in case of detecting high speed air target the range migration and Doppler ambiguity estimation will happen in the process of targets parameters estimation, these problems occurs due to the high relative speed between the targets and the airborne radar specially in the presence of jamming and clutter effects that will be more heavily in case of using airborne radar than using ground radars, this paper proposes a new parameter estimation method for compensation of the range migration and Doppler ambiguity estimation based on Optimum Space Time Adaptive Processing (OSTAP), Second Order Keystone Transform (SOKT), and the Improved Fraction Radon Fourier Transform (IFrRT).
