One of the benefits of digital technologies progress is an ability to realize digital radar signal processing and an ability to implement software defined radar. The aim of this paper is the analysis of utilizing software and hardware resources in role of radar signals generator. The evaluation criterion is the distortion of generated data for different sampling frequency values and thus for different bandwidth values. From the results achieved, we can state, it is possible to generate real polyphase intrapulse modulated radar signals by utilizing selected software and hardware resources.
