Design of a direction finder based on the output of parallel hydroacoustic surveillance system

The problem of synthesizing a direction finding algorithm based on sample composed the output signals limited number channels scanning sonar system is considered. formulated as search for maximum likelihood function by its lattice representation. Options using optimal and quadratic interpolation are errors displacement loss potential accuracy estimated depending dimension, angular step scanning, amount target movement within measurement interval. advantage proposed approach shown in terms compared to traditional constructing paths Guanella's technique.
