The problem of clutter cancellation in a non-Gaussian environment is becoming more and more important in modern high-resolution radars, owing to uncertain clutter statistics. To evaluate the MTI canceller performances, in the paper we examine an intermediate frequency model which gives, in the video frequency, a signal with log-normal (LN) probability density function (PDF). The improvement factor needed to obtain optimum detection performances in a multiclutter environment will be evaluated.
