This paper studies the effect of estimating the interference rank on the detection performance of several rank reduced space-time adaptive processing techniques in airborne radar applications. Focus is on the relationship between the rank of the interference and the order of properties are explored. The CFAR properties are explored. The parameters considered are the number of barrage noise jammers, the decorrelation time of the clutter, and aircraft crab angle. Both simulations and measured data results are provided.
