          Abstract

          In this paper, the false target discrimination strategy of air surveillance radar is studied. Aiming to distinguish false target which can form certain track such as clutter residual false track or false track deception, a novel method based on track velocity modification and frequency spectrum analysis is proposed here, which can provide a great potential approach for solving the false target discrimination puzzle. The discrimination issue is concluded as a problem of bivariate test of hypothesis, and the likelihood ratio formula is deduced with the way to calculate the judge threshold also proposed. The validity of the novel method is verified by experimental results of real surveillance radar data.
