Abstract: : A brief description of the radar CAD software modules responsible for this functionality is given. The module of engineering calculations and simulations allows you to set the scenario of the interference-target situation and conduct a complete, close to reality, simulation of the behavior of the radar in combat conditions. The visual functional editor provides the ability to create a radar simulation model in the form of a graph of streaming calculations from interconnected parameterizable blocks. The library of parameterizable modeling blocks contains modeling blocks designed for calculations and modeling of structural and functional parts of developed radar stations, complexes, systems. Simulation model of an active single-position pulse-Doppler sector-observation radar with electronic beam scanning was created. The following algorithms are implemented in the model: the sum-difference monopulse direction finding algorithm, the MUSIC superresolution direction finding algorithm, and the projection adaptive spatial filtering algorithm. A simulation experiment was carried out with a radar model in three scenarios of an interference-target environment, which differ in the presence of interfering signals. Analysis of the results of the simulation experiment shows that the operation of the algorithms corresponds to the theoretical prediction. The abilities of radar CAD presented in this article can be used by specialists in radar and signal processing.
