Abstract

A method includes receiving radar parameters from a unit under test (UUT). The method also includes generating a simulated radar return for the UUT using at least one graphics processing unit (GPU), where the simulated radar return includes digital signals. The method further includes controlling a timing of output of the simulated radar return to the UUT using at least one field programmable gate array (FPGA) carrier. The method also includes converting the digital signals into analog signals using multiple digital-to-analog converters (DACs). In addition, the method includes transmitting the analog signals to the UUT.
