SMALL SAMPLE SEQUENTIAL DETECTION OF RICEAN DISTRIBUTED SIGNALS,
Abstract
A method is considered of evaluating small average sample size (1.0 to 1.2) sequential detection of Ricean distributed signals. Useful approximations for this method of testing were formulated by A. Wald using large average sample sizes. These relationships do not hold for small average sample sizes. A solution is presented for this method of testing and the results compared to Wald's approximation. In addition this testing method is compared with fixed sample size and null-zone detection (sequential test without memory). It is shown that sequential detection has a significant improvement over fixed sample testing and may be approximated by the null-zone detector for small average sample sizes. Some remarks are included on truncating the sequential detector after the second sample. The distribution dealt with in this report, the Ricean, describes the envelope of a sine wave plus noise, common in many physical situations for example radar target detection. (Author)
