  1. On data level, it is firstly explored fusing signature data from sparse - band collocated radars to obtain wider band target frequency response. the most difficult problem which restricts the fusion process is the lack of mutual coherence between the various radar subbands

    在數據層，首先探索了對多個配置在同一地方的不同頻帶雷達測得的目標頻率響應進行融合，以獲取更寬頻帶目標頻率響應的方法。
  2. Radar jammers will obscure your radar signature, mobile flak cannons can provide protection against aerial assaults, and mobile shield generators can deflect incoming fire

    雷達干擾機可以抹消你的雷達信號，移動防空跑可以提供對于空襲的保護，移動力場發生器可以偏轉來襲炮火。
  3. Once again, rival technology for manned aircraft stole the thunder : stealthy designs to reduce the radar signature, precision weapons such as cruise missiles and laser - guided munitions and new sensors such as synthetic - aperture radar that could look through clouds

    對手的人工駕駛飛機的科技再一次先聲奪人：為減少雷達信號而進行的秘密設計、諸如巡航導彈與激光導向的軍需品之類的精密性武器，以及一些新型傳感器，諸如可透視雲層的合成光圈的雷達。
  4. Terrain slope information can be drawn from polarimetric synthetic aperture radar ( sar ) two - dimensional image, so that three - dimensional image can be generated. it differs from two - pass or repeated trace insar that uses interference phase method to obtain topography height. the p - sar three - dimensional image technology uses the stokes matrix formed by two - dimensional images resolution cells, then applying polarimetric synthesize to stokes matrix can produce polarization signature of the scatter cross - section a - (, x ) for any ( ellipticity ) and ( orientation ) polarization state

    這種方法不同於重復軌道和雙通道insar系統，不是利用干涉法提取高度信息，而是利用極化sar二維圖像各分辨單元的stokes矩陣，通過極化綜合估計每個分辨單元的共極化散射特性和交叉極化散射特性（極化指紋） ，以及共極化散射特性最大值時對應的極化橢圓度x利極化橢圓方向角，求解地形的高度輪廓。
  5. Based on the uwb radar system, the emitting waveform design and signature waveform detection are discussed respectively in this paper to realize the detection and discrimination of targets

    本文在超寬帶雷達體制下分別從發射波形設計和特徵波形檢測兩個角度來實現目標的檢測和識別。
  6. But when the high - tech bombers got drenched during missions in the balkans, the tape used to fill seams in the composite skin often came loose. that enlarges the radar signature

    但當該機在巴爾干半島執行任務時，遭到雨淋后，用於填充復合材料外殼接縫的膠帶往往會松脫，從而擴大了飛機的雷達信號特徵。
