Study on the Quantization Error of a Coherent Inverse Synthetic Aperture Radar Digital Moving Target Simulator
When generating the simulation echo by an inverse synthetic aperture radar(ISAR)digital moving target simulator(MTS),the quantization error of time delay caused by the digital-to-analog(DA)devices will destroy the consistency between the simulated echo and the ideal echo,result in image blur.In order to eliminate the quantization error,two compensation approaches are proposed in this paper.The quantization error between the simulated echo and the ideal echo and its influence on the imaging results are analysed.As the quantization error is fixed,the compensation methods in the time domain and the frequency domain are introduced,respectively.The simulation results show that the proposed method is effective and have excellent performance.
