Popis: | In the process of realizing software-based radar, digital-to-analog converter plays an important role. It is the only bridge connecting analog world and digital world. It is a vital step of radar signal entering digital processing. Therefore, the performance of ADC will have a direct impact on radar signal processing, the process of detection and estimation, and play an important role in software radar implementation. This paper analyzes and evaluates the effect of the speed and accuracy of the digital-to-analog converter on the subsequent radar signal processing. Data simulation using MATLAB software to simulate ADC sampling, quantization process in a series of performance indicators, Focusing on the analysis of the impact of digital-to-analog conversion in the process of quantization noise and clock jitter on radar systems, including the impact on the signal to noise ratio, the impact of the range of the power of radar. Finally, the correctness of the theory is verified by simulation analysis. |
