Influence of Power Spectral Density Distortions of Noise Radar Signal on its Ambiguity Function

In this paper we discuss various distortions of energy spectrum of an ergodic random signal and their influence on the main parameters of estimation of autocorrelation function with the aim of searching of signal optimum characteristics, which would allow to minimize losses in resolution and detection abilities at a maximum diminution of a minor-lobe level of ambiguity function. Besides, in the present paper we have considered influence of parameters of noise sounding signals processing with prescribed power spectrum shape on the shape of the correlator response and accuracy of correlation function estimation.
