Popis: The use of existing hardware (e.g. software defined radio) above given frequency range and resulting undersampling necessity is and will represent very often practical question. In this article our concern is to describe most critical details of the radar digital signal processing modelling, micro-Doppler detection of small unmanned aerial vehicle motion in particular. Mathematical model of the radar echo signal generation, undersampling theoretical analysis and preconditions definition for digital signal processing model in MATLAB-Simulink represents the core work. This step is very important for further programming - software implementation with software defined radio. The digital signal processing model as the output shows practical limits that demonstrates realistic micro-Doppler detection of small unmanned aerial vehicle motion. Theoretical results and practical example can be used in other software defined radio applications with respect to given practical hardware parameters.
