radar antennas 中文意思是什麼
radar antennas
解釋
雷達天線-
In addition to the conventional techniques such as low sidelobe antennas and displaced phased center antenna ( dpca ), there has been great interest in space - time adaptive processing ( stap ) because it can suppress clutter effectively and improve the detection performance of airborne phased array radar evidently
除了採用低副瓣天線、偏置天線相位中心（ dpca ）等傳統雜波抑制技術，能夠有效提高機載相控陣雷達地雜波抑制能力和動目標檢測性能的空時二維自適應處理（ stap ）受到了廣泛關注。 -
The prm is basically a monopulse secondary surveillance radar ( mssr ) that employs electronically - scanned antennas configured in a circular array
精密跑道監系統基本上屬單脈沖二次監察雷達，但採用排列成形的電子掃描天線。 -
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。 -
Radar sets generally employ large antennas to produce narrow beams in much the same way as a search - light reflector
通常雷達採用大型天線以產生狹窄波束，其方法基本上與探照燈反射鏡相似。 -
Over - the - horizon radar ’ s beam - frequency is high frequency band and its wavelength is so long that the annate ’ s characters are very complicated when applicated on the ship. the character of coupling between cells and the environment must be measured to compensate in the radar signal process step. the ship - based over - the - horizon radar uses cfa ( crossed field antenna ) as array antennas ’ cell
艦載超視距雷達使用高頻信號作為發射頻率，其波長較長，在艦船有限的空間內，陣列天線的陣元之間的耦合與陣元與背景之間耦合都十分嚴重，必須測量陣列天線通道的幅相一致性，作為雷達信號處理的補償參數。 -
Along with the electronic warfare demand and the requirement of probing and tracking outer - space objects, phased array antennas have become developmental mainstream of the applied radar antennas
隨著電子對抗技術的發展和外空間目標探測、控制的需要，相控陣天線已經成為當今實用雷達天線發展的主流。 -
At the present time, phased array antennas have already become the main develop - ment direction of radar antennas
目前，相控陣雷達天線已成為當今雷達天線的發展主流。
