zero azimuth 中文意思是什麼
zero azimuth
解釋
零方位角-
The radar which is embedded on platform sidelooking, but the platform will be disturbed by airflow inevitably. so, the radar will have a small sloping angle, thereby, the doppler centroid that is not zero and doppler frequency rate need to be estimated from the raw echo data in order to focus in azimuth commendably
場景成像的合成孔徑雷達一般是正側視放置，但是載機不可避免的要受到各種擾動影響，雷達會有一定的斜視角，從而導致了多普勒中心頻率不為零，多普勒調頻斜率也隨著雷達斜視角改變。 -
Based on the rigorous coupled wave theory, the phenomenon that the zero order reflection efficiency of rectangular subwavelength grating varies with the wavelength is studied when incidence angle, azimuth and grating parameters are variant
摘要從嚴格耦合波衍射理論出發，在不同入射角、方位角和光柵參數下的情況，計算了矩形亞波長光柵零級反射效率隨入射光波長的變化。
