Robust Sequential Detection Using Arrays.

Abstract

I will be discussing a procedure for designing a robust sequential detector using an array of M Hydrophones. The technique has the advantage of not requiring knowledge of the noise distribution. However, a set of quantiles and related functions of the noise distribution are assumed known. In applications, the quantiles and related functions are usually estimated by stochastic approximation techniques. Initially, I will present a detector structure which was derived from the loglikelihood ratio assuming independent samples and discuss its advantages in nongaussian noise. Then I will discuss a procedure to maintain fixed performance levels under dependent sampling. (Author)
