Оценка числа каналов приёмника-обнаружителя сигнала управляемого пассивного рассеивателя с неизвестными параметрами фазовой модуляции

Abstract

The synthesized algorithm for detection of a signal controlling passive scattering with unknown parameters of phase modulation is observed on the background of a harmonic signal and Gaussian noise. The method of estimating the quantity of channels of the receiver in computational maximize functionality likelihood ratio for unknown parameters, by explicitly represent a Gaussian random process of its counting is proposed. Two theorems about the averaging works bilinear forms of different dimensions are proved. The formulas for estimating the quantity of channels of the receiver-detector signal controlling passive scattering are given.

Синтезирован алгоритм обнаружения сигнала управляемого пассивного рассеивателя с неизвестными параметрами фазовой модуляции, наблюдаемого на фоне гармонического сигнала и гауссовского шума. Предложен способ оценки числа каналов приемного устройства при численной максимизации функционала отношения правдоподобия по неизвестным параметрам, путем однозначного представления гауссовского случайного процесса его отсчётами. Доказаны две теоремы об усреднении произведения билинейных форм различной размерности. Получены соотношения для оценки числа каналов приёмника-обнаружителя сигнала управляемого пассивного рассеивателя.
