角反射器天線Corner reflector antenna
角反射天線At this moment, both the direct signal and the reflected one impinge into the array, and make the amplitude and phase of the echo change, which cannot be separated from the direct one, thus cause server errors of elevation ’ s estimation, even the failure of tracking
此時直達信號與反射信號同時進入天線,造成回波幅度與相位的變化,並且這種變化不能從直達信號中分離出來,從而造成目標仰角估計的嚴重誤差,甚至引起跟蹤的失效。At different scanning angles, by analyzing the effects that the surrounding elements on the middle one, we conclude that the reflected vote of the middle element decreases, that ’ s the loss of reflected power decrcases, so the input power will increase
結果發現,在不同掃描角下,中心陣元的反射電壓得到減小,因此,達到了反射功率損耗減小,傳向天線單元輸入端功率增加,天線性能提高的目的。The mutual coupling between phased array antennas elements causes the loss of reflected power. following the changes of scanning angle, mutual coupling between elements will also change, so the comensation of mutual coupling should become difficult
相控陣天線單元間由於互耦效應引起的反射功率損耗,隨著掃描角的變化而隨之發生變化,這給互耦補償帶來了極大地困難。A method known as asymptotic waveform evaluation ( awe ) is firstly employed to analyze the array impedances versus the operating frequencies. the input impedances of the array in several different structure are calculated. by using the awe, the calculation time is much smaller than that by using mom
首次將漸進波形估計( awe )技術用於陣列天線的分析,計算了圓環陣列、圓環反射陣列、線形陣列和三角形陣列的輸入導納與頻率的關系曲線,與傳統的矩量法相比,大大地加快了速度。分享友人
