寬角掃描器 的英文怎麼說
中文拼音 [kuānjiǎosǎomiáoqì]
寬角掃描器
英文
large-angle scanner-
However, the instantaneous bandwidth of signals is restricted for general phased array because of its transition time and aperture effect
但是，基於移相器的普通相控陣天線在進行寬帶寬角掃描時，由於渡越時間和孔徑效應的影響，使信號的瞬時帶寬受限。Ae signals released from different lay - ups composite specimens were acquired by a wideband transducer, and fracture surfaces of the specimens were observed by scanning electron microscope ( sem )
寬帶傳感器記錄了不同角度纖維鋪層的復合材料試樣在拉伸破壞過程中的聲發射信號，用掃描電子顯微鏡（ sem ）觀察了試樣的幾種典型的損傷破壞斷面，對比分析了不同類型的損傷機制。As ttd ( true time delay ) is utilized in optically controlled phased array at sub - array level to replace the phase shifter in general phased array radar system, and make time delay compensation at sub - array level, which can reduce aperture effect considerably and make the broadband and wide - angle scanning of phased array antennas come true
由於光控相控陣雷達在子陣級上引入實時延時線ttd （ truetimedelay ）取代常規相控陣雷達中的移相器進行子陣級的延時補償，大大減輕了孔徑效應，使相控陣雷達實現了寬帶寬角掃描。
