  1. 3. after studying deeply the multi - antenna sar mtdi based on displaced phase center antenna ( dpca ), a new double - antenna method is proposed which remedies the shortcomings of conventional ways. the method need n ' t meet the constraint condition that conventional ways must meet and can suppress ground clutter effectively and detect moving target

    針對常規dpca方法的缺點創新性的提出了一種新的雙天線動目標檢測方法，建立了該方法的檢測模型並對該方法進行了有效的驗證，該方法不合成孔什雷達動口標檢測和成像研必滿足常規方法所必須滿足的限制條件就能夠進行動目標檢測，提高了dpca的實用價值。
  2. This paper discusses three slot - coupled microstrip antennas with high dielectric constants based on gps ( global positioning system ) receiving antenna. they are separately with slots of oblique, t shape, and l shape

    本文以全球定位系統（ globalpositioningsystem ，簡稱gps ）接收機微帶天線單元為研究對象，探討了三種高介電常數縫隙加載正方形貼片的天線特性，分別是斜縫， t形縫和l形縫。
  3. The author ? major contributions are as follows. 1. with the performance requirement ( the pattern of the antenna, the rang of scanning angle, the maximal sidelcbe level and the beam ~ vidth ) givcn, a method is presented to determine the basic parameters of a serpentine feed, which includes the distance and ~ vaveguide length bet ~ veeii t ~ vo couplers, the size of the arrays and the number of components

    根據天線的工作頻帶、掃描范圍、副瓣電平、半功率寬度等技術指標要求，給出了確定波導慢波線基本結構尺寸的計算公式，即對相鄰單元之間的空間距離、耦合器之間的饋線波導長度、陣列的大小和單元數的計算。
  4. Secondly, because the band of the traditional microstrip antenna is very narrow. and the isolation can ’ t meet the requirement when the coaxial - line feeding is used to realize the dual polarization. the following work lays heavy stress on analysis of the way of widening the bandwidth and developing the isolation of the antenna

    傳統的微帶天線帶寬較窄，採用普通同軸線饋電實現雙極化的時候，隔離度不能夠滿足天線的要求，所以在接下來工作中，重點分析了微帶天線頻帶展寬和隔離度改善的方法。
  5. The way of widening the band is realized by employing the inverted parasitic patch and the thick and low dielectric constant substance. with this treatment, the relative band of the antenna can be widened up to 20 %. and by adopting the way of two h - slots arranged in a “ t ” configuration, the isolation is improved

    微帶天線的頻帶展寬通過採用倒懸寄生貼片和較厚的低介電常數的介質來實現，經過這樣處理后的天線帶寬可以達到20 %以上;而隔離度的改善則是採用了兩個h形縫隙排列成「 t 」型結構。
  6. Key technologies are first introduced here such as the phased array antenna theory, dbf ( digital beam forming ) theory and the configuration of transmit and receive ( t / r ) modules. then part of analog circuitry is optimized with the digital technology. cell circular microstrip disk antenna successfully developed based on the theory of microstrip antenna, the four - celled circular microstrip disk antenna arrays are designed, simulated and analyzed with eda tools - hfss, opt1metrics

    本文以相控陣雷達組成為主軸，逐一對相控陣雷達關鍵技術中的天線陣原理、數字波束形成（ dbf ）技術和收發（ t r ）組件組成進行詳細的分析，利用數字技術對傳統相控陣雷達設計方案中的模擬電路部分進行改進；在理論設計單元圓形微帶貼片天線單元的基礎上，利用微波模擬軟體hfss和optimetrics對四單元的圓形微帶貼片天線陣進行設計與模擬；對相控陣雷達的幅相監測技術進行理論分析和討論，選擇最佳的幅相監測方案。
  7. Don ' t put antenna outside in thundering and raining days

    打雷或下雨時不要使用是外天線。
