Multisignal Direction Finding at One Frequency as Problem of Signal Disintegration for Sum of Components

An ill-defined problem is considered of the multisignal direction finding of radio sources, radiating at one frequency, by means of antenna systems consisting of near-omnidirectional elements (vibrators). A method is offered for solving the problem of direction finding based on the algorithm of estimation of powers of the sum of exponential functions. Algorithms of point and interval estimates of amplitudes and bearing of signals are given.
