radar range unit 中文意思是什麼
radar range unit
解釋
雷達測距裝置-
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
由於fft的實質是頻率在單位圓上的等間隔采樣,其采樣間隔限制了雷達的實際測距精度,使得其測距精度與其距離分辨力處于同一量級。
