  1. First, it was taken that a discuss about the effects of geometry parameters of each piezocrystal on direction parameters ( main lobe width, side lobe amplitude, elimination of grating lobes ), amplitude of ultrasonic pressure, element viberation pattern, mutual radiation among elements, efficient test regions, ability to keep accurate and near - field distance and so on. based on the direction of ultrasonic field in ulpa deduced by ourselves. in addition, on the base of integrating all kinds of factors, it was put forward that the principle and method for optimized design of geometry parameters of piezocrystals in ulpa transducer, and its design programme and interface were compiled

    首先在推導超聲相控線陣換能器聲場的指向性的基礎上，就各個晶片幾何參數對指向性指標（主瓣寬度、旁瓣幅度、消除柵瓣） 、聲壓幅值、陣元振動模式、陣元間互輻射、有效檢測區域、精確控制能力、近場長度等方面的影響進行了論述，並在綜合各方面影響的基礎上，提出了晶片幾何參數優化設計的原則和方法，編寫了設計程序和界面。
  2. Because an antenna beam has certain width, and the antenna on the earth will point to the adjacent satellites at its side lobe, the transmitting antenna may create interfering radiation ( which is known as uplink adjacent interference ), and the receiving antenna will also be interfered ( which is known as downlink adjacent interference )

    由於天線波束具有一定的寬度，地面發送天線會在指向鄰星的方向上產生干擾輻射（上行鄰星干擾） ，地面接收天線也會在鄰星方向上接收到干擾信號（下行鄰星干擾） 。
