Communications and Signal Processing ICCSP, Chengdu, 2015, pp. Sundaresan S., Anjana C., Zacharia T., Gandhiraj R. Basic advantages (including versatility and availability) and disadvantages (including time consumption and the absence of project flexibility) of the discussed systems are stated their mutual comparison is carried out.

The computational capability and time consumption related to operation of the studied systems of SDR programming are analyzed within operation and configuration of examples. Diagrams for the generated FMCW signals with the chosen parameters in time and frequency area are drawn. By means of the algorithm of such signal generation, models of FMCW generators are developed and operation of the studied SDR programming systems is estimated. Examples are given for application of these tools in research of radar systems based on the signal with frequency-modulated continuous wave (FMCW) generation. The paper describes their structures, interface, models of basic components and system requirements to these programs. Two software tools for programming SDR systems are analyzed: Lab VIEW и GNU Radio. The paper deals with the question of choosing the software tools for modeling and design of radar systems.

The software-defined radio technology gives an opportunity for all radio engineers to make radar systems by using the SDR based program models. This moment is clearly expressed in the process of development and wide implementation of the technology of the software-defined radio (SDR). However, details in integration functions indicate that MATLAB has more accurate results while OCTAVE may return incorrect answers if the functions for integration are inappropriately employed.The main trend of advanced radar systems is the transition to digital technology. By comparing the results of tests in signals (including the Fourier transform, Fourier series, power and energy) and systems (including the random variables and autocorrelation), these two software platforms are highly compatible with each other in most cases. Although they are both used for scientific calculation in many fields, there still exist some differences in details between them. This dissertation examined the similarities and differences between two software platforms MATLAB and OCTAVE in signal-and-system functions.
