Radar Signal Environment Simulation Based on Quadrature Multiple Waveform Synthesis Method

The principle of multiple quadrature waveform synthesis (MQWS) is introduced, which is based on the theory of quadrature modulation. Its adaptability to pulse signals is analyzed. Combined with pre-saved waveform data, this method can be used in radar signal environment simulation and it can simplify the requirement for the hardware implementation with general-purpose and flexibility characters. The realization experiments show that it can fulfill the signal's simulation of various radar types.
