本文对存在线谱的快速目标的多普勒频移问题,给出了一种用短信号段加补零段做FFT三维图的测量方法;计算机算出的实际快速目标的多普勒频移-时间曲线,与预知条件下理论曲线的趋势良好一致。
This paper gives a method to measure the Doppler frequency shift of the fast target with line spectrum by using the short signal segment plus the zero segment to do the FFT three-dimensional graph. The Doppler frequency shift of the actual fast target calculated by the computer - The time curve is in good agreement with the trend of the theoretical curve under the predicted condition.
