A waveform distortion model in time domain which has been recognized by In‐ternational Civil Aviation OrgIniZation (ICAO) is introduced in this paper .Modeling method of three threat signal models of waveform distortion in time domain in FPGA for navigation signals is proposed , too . Matlab‐based simulation and FPGA‐based implementation for waveform distortion model in time domain is presented ,and the two results were compared . Thus ,the tests show that the mean relative error not more than 0.5% for the two results .
