Detection performance of an adaptive MTD with WVD as a Doppler filter bank

The Wigner–Ville Distribution (WVD) has been gaining importance in the recent years for the analysis of time varying signals (B. Boashash, in: Simon Haykin (Ed.), Advances in Spectrum Analysis and Array Processing, Prentice-Hall, Englewood Cliffs, NJ, 1991). In this paper, an adaptive moving target detector (AMTD) based on WVD as a Doppler filter bank has been introduced. The proposed AMTD processor has been simulated in the presence of Gaussian and non-Gaussian clutter environments. The preliminary investigations reveal that the proposed processor performs better in terms of probability of detection than the existing moving target detector (MTD) processors.
