Abstract :
A root test for signal detection based on a family of autoregressive (AR) spectral estimates is evaluated. It is observed that the root test fails for the strong narrowband noise case and is asymptotically inconclusive. A ratio test is also studied. The two AR spectra with order n and 2n are dependent. since they use the same first n correlation information. It will be difficult to find the joint density function of the ratio of the two AR spectra above. An example is included.<>
