  1. Coherent pulse radar

    相干脈沖雷達
  2. Synthetic aperture radar ( sar ) is a kind of coherent pulse radar which appeared in 1950. it can improve space resolution by fully using the signals " coherence

    合成孔徑雷達（ sar ： syntheticapertureradar ）是20世紀50年代發展起來的一種相干雷達。
  3. Advantages, disadvantages and limits of arm are thoroughly examined using signal processing methods. based on the above, incoherent and coherent two - point - source decoy methods and modified coherent two - point - source decoy methods to deflect arm are brought forward. arm ’ s homing heads are generally of mono - pulse structure, so coherent two - point - source ’ s interference resembles that to mono - pulse radar except that interference to radar belongs to far field scope, but interference to arm varies from far field to near field because relative distance drastically changes between the homing head and the two - point - source with missile ’ s homing head continually approaching the target

    Arm的導引頭一般為單脈沖體制，因此，相干兩點源對導引頭的干擾類同於對單脈沖雷達的干擾，不同的是:對雷達的干擾都是遠場，而導引頭隨著導彈不斷接近目標，兩點源與導引頭的相對位置發生劇烈變化，由遠場變化到近場;導引頭天線口面上的合成場也發生了大的變化，相位波前的畸變產生干擾，這就是相干兩點源誘偏的基本思想。
  4. The fourth section studies the modeling of broad band blocking jamming and coherent jamming, and analyses the principal of coherent jamming and the factors of influencing the jamming effect is provided. the performance of pulse doppler radar seeker is simulated when certain jamming methods is exerted. a pulse doppler radar seeker simulation system is established, by using the simulation system the performance of pulse doppler radar seeker is evaluated when jammed

    第四部分研究了寬帶阻塞式干擾和相干干擾的建模問題，並分析了相干干擾作用原理，給出了影響干擾效果的主要因素及次要因素，模擬了脈沖多普勒雷達導引頭在寬帶噪聲干擾情況下的截獲和跟蹤性能，模擬了相干干擾對脈沖多普勒雷達導引頭跟蹤性能的干擾效果。
  5. In the paper, a coherent video signal simulation is applied to model and simulate a pulse doppler radar seeker

    本文採用相干視頻信號模擬方法對脈沖多普勒雷達導引頭進行了建模和模擬研究。
  6. The drfm permits generation of appropriate radar returns to chirped, frequency coded, phase coded, pulse coded, or other similar type coherent radars with pulse to pulse or cw modulations

    在另一些情況下，需要將不同於接收到的雷達信號的特徵的信號返回雷達系統，用來進一步使雷達系統混淆工作。
