The large size not only makes the radar easy to be detected, but also increases engineering costs for the ‘ golden seashore ’ it occupied. furthermore, large size brings serious troubles in the antenna setting - field choosing, installation and maintenance. distributed array is one of the solution way
過大的陣列尺寸不僅易於暴露陣地目標,還因佔用「黃金海岸」提高了工程造價,同時也給雷達陣地的選擇以及雷達系統的管理、維護帶來許多不便,分散式陣列是解決途徑之一。Thus the main and auxiliary polarization radars form a side lobe canceller system. based on the modeling of this system, an anti - jamming filter algorithm in the polarization - spatial domain is brought forward
針對接收全極化雷達,在其旁邊放置全向雙極化正交陣列天線與雷達構成旁瓣對消系統,並根據系統模型提出了極化域-空域聯合濾波抗干擾演算法。For the high - speed digital signal processing, the structure of fpga and dsp is widespreadly adopted. dsp is more featured in the implementation of complicated algorithm, while field programming gate array ( fpga ) shows more advantage in its flexibility of design, simplicity of system configuration, modification and maintenance. in the paper, the hardware system of the spaceborne radar is based on the structure of fpga and dsp, of which the signal processing part is accomplished with one fpga chip and multi dsps
Dsp適合完成結構復雜的演算法;現場可編程邏輯陣列( fpga )適合完成高效、演算法固定的任務;與專用集成電路( asic )相比, fpga優點主要在於其很強的靈活性、可在線配置、修改和維護方便等優點。本文工程中的星載雷達信號處理和控制系統就是採用dsp + fpga的方式。其中信號處理採用的是xilinx公司的virtex -和virtex系列fpga和多片analogdevices公司的tigersharcts101的硬體電路結構。With the development of radar technology, the intrinsic defects of traditional antenna array greatly restrict the system performance ; therefore research on the compact receiving array of hfswr becomes urgency
隨著雷達技術的發展,傳統大型陣列天線固有的缺點已經成為了制約系統性能的一個瓶頸。因此亟需開展高頻雷達小型化陣列天線的研究工作。In theoretically, analog optical fiber link can carry out the signal transmission transparently. however, because of the limit of the component level, during the transmission and distribution of the radar signal, noises and interferences from the optic - link may distort the signal and affect the system performance and the array signal processing
模擬光纖鏈路理論上可以實現信號的透明傳輸,可由於受到器件水平的限制,在整個光傳輸和分配過程中,雷達信號必將受到來自光路噪聲或干擾的污染,從而產生某些畸變和失真,這些非理想因素必然對陣列系統的性能指標和陣列系統的信號處理產生影響。分享友人
