Annotations languages:

Methodology of synthesis of coherent multifrequency signal, allowing for the set number of frequency constituents and form of amplitude - frequency spectrum of multifrequency signal, formed by the method of angular modulation, is offered in the article, to get a modulating function which allows to form a signal with the required cross - correlation properties at the one channel forming. It is shown that the indicated procedure of synthesis allows to reduce the level of sidelobes of autocorrelation function of multifrequency signal to the level, allowing to provide effective work radio-location systems seashore basing in the conditions of influence of unpremeditated passive hindrances.
Keywords: multifrequency signal, amplitude-frequency spectrum, phase-frequency spectrum, autocorrelation function, angular modulation, unpremeditated passive hindrances
