Abstract

Abstract:

Repeater jamming brings a great challenge to moving target detection for airborne radar. It not only causes a false alarm but also raises the threshold of the detector, which reduces the probability of detection. A method based on maximum likelihood estimation to detect a moving target for airborne radar under repeater jamming environment is proposed. Firstly, the spatial steering vector of repeater jamming is estimated. Afterward, the maximum likelihood method is utilized to estimate the amplitude of the target, whose estimated amplitude is used to detect the moving target. Simulations show that this method is capable not only of suppressing the clutter but also of reducing the effect of repeater jamming from the sidelobe on moving target detection. Moreover, it can reduce the effect of repeater jamming from the mainlobe to a certain degree.

Key words: airborne radar, moving target detection, maximum likelihood estimation, repeater jamming
