  1. Using coordinate transformation method, the formula of imv on every point of image plane was deduced, and it included almost all motorial factors : the flight velocity of aircraft, roll, pitch, yaw, camera ' s scan and so on. thus, it is a precise formula, and it is also applied to frame cameras and push _ room cameras with array ccd

    利用坐標系變換的方法可推出像面上各點的像移速度公式，該公式包含了幾乎所有的運動因素：飛機的前向飛行、飛機的姿態角變化、相機自身的擺掃運動等等，是精確的像移速度公式。本公式同樣適用於畫幅式航空相機和線陣ccd推掃型航空相機。
  2. Linear array can only provide an azimuth scan ranging from 0 to 180 degree, while circular array from 0 to 360. by means of recurring moving array excitation, circular array controls the beams ’ orientation simply and neatly, creating a perfect pattern in azimuth and an ideal pattern in pitch

    線陣只能有180的掃描范圍，而圓形陣列能夠提供360方位角，通過循環移動陣列激勵，簡單而靈活地操縱波束的方位，能夠在方位上產生沒有方向性方向圖，而在俯仰方向上也有一個理想的方向特性。
