ftt造句

Lfmcw radar adopts the receiver with the structure of “ homodyne - fourier ” , and acquires the range spectrum after its if signal is sampled , and then processed by ftt
Lfmcw雷达采用了“差拍-傅立叶”接收机结构,其回波中频信号经数字采集后进行fft处理,从而获得雷达的距离谱。
Ftt makes the frequency sampled at a same frequency interval on unit circle , and the frequency interval limits the practical range - precision of the radar , and makes range precision at an equivalent level with range - resolution
由于fft的实质是频率在单位圆上的等间隔采样,其采样间隔限制了雷达的实际测距精度,使得其测距精度与其距离分辨力处于同一量级。
It's difficult to find ftt in a sentence. 用ftt造句挺难的
