Increase in the noise-resistance of the multichannel rts with complex amplitude-phase-manipulated signals and time rejection of power disturbing reflections from the surface placed under

The object of investigation: the RTS with complex quazicontinuous signals and multichannel correlative processing of signals. The purpose of the work: the development of method of the time rejection of the multichannel RTS with quazicontinuous signals orerating under the conditions of the power disturbing reflections, as well as the problem of synthesis of the ternary signals with good properties of the pulse autocorrelation function (PACF). For the first time, obtained have been the analytical evaluations: of the mean-square level of the side lobe of the uncertainty body, middle coefficients of the reception and superposition, middle and potential values of the ratio signal-nois in the case of application of time rejection of the power disturbing reflections from the near zone of the surface placed under. The methods of selection of the optimum parameters of the multichannel RLS with time rejection of disturbing reflections have been suggested, developed has been the program package intended for evaluation of the noise-resistance RLS with time rejection of disturbing reflections, the algorithms of synthesis of the ternary and binary chains with single (by the module) level PACF and minimum peak-factor have been developed. The results have been introduced in the experimental model RLS. The introduction of the time rejection method allows to increase the mean ratio signal-noise by 10 to 20 dB for the remote targets (within the limits of scale). The field of application: the radiotechnical systems with complex signals operating under the conditions of the power disturbing reflections caused by the surface placed under (with small slip angles)Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
