理论与实验研究结果表明该方法可消除渡越时间效应、湍流和采样单元内流速梯度造成的频谱模糊。
Theoretical and experimental results show that this method can eliminate the Doppler ambiguity spectra produced by transit-time effect, turbulence and velocity gradient in sample volume.
但是，基于移相器的普通相控阵天线在进行宽带宽角扫描时，由于渡越时间和孔径效应的影响，使信号的瞬时带宽受限。
However, the instantaneous bandwidth of signals is restricted for general phased array because of its transition time and aperture effect.
由于孔径效应和孔径渡越时间的限制，传统的相控阵雷达难以在大扫描角下实现大瞬时带宽。
Due to the restriction of aperture effect and the aperture traverse delay, it is difficult for a conventional phased array radar to get wide instantaneous bandwidth under wide scan scope.
