doppler information meaning in Chinese
多普勒信息
Examples
- Based on the coherent modulation model , doppler information is obtained by using ad633 analog multiplier and active low pass filter ; 3
以相干检波一般模型为基础，采用ad633模拟乘法器和有源低通滤波器实现了对多卜勒信息的提取； 3 - Its high resolution in range is fulfilled by using pulse compression method . its high resolution in azimuth is achieved by utilizing the doppler information among the signals received by sar at different locations . hence , the acquired image of the targets is of very high resolution
它采用距离向的脉冲压缩技术和方位向不同位置上接收到的脉冲间的多普勒信息来获得两维的高分辨率，从而得到高分辨率的目标图像。 - Firstly , the theory and the architecture of hardware system are described , secondly , the steps of the signal processing are discussed in detail . based on the experiments and the characteristics of the signal , we pre - process the signals with band - pass filter , proportional amplifier and coherent demodulator . after sampling and analysis doppler information , we display the final results distinctly to alarm in time
然后，结合系统中各主要部分的任务，详细介绍了信号处理的各个步骤：通过实验比较，并结合接收信号的特点，选用带通滤波器、比例放大器、相干检波等技术对信号进行预处理；然后对获得的多卜勒信息进行采样和频谱分析；最后，用比较直观的形式显示数据结果，以及时准确地告警。
