Abstract
Methods and systems for generating and utilizing an emulated radar data cube are disclosed. An emulated radar transmission waveform is defined based on expected radar performance. A virtual real world scenario comprising one or more virtual target objects is constructed. The virtual target objects emulate reflection and scattering properties to an input radar wave of real world objects. Operations of radar transmit and receive channels including an antenna array and free space propagation are emulated to obtain emulated raw radar data. Data processing is performed on the emulated raw radar data to build an emulated radar data cube. The emulated radar data cube is utilized to test a radar perception algorithm.
