  5. Now the two issues we are confronted with are : first, a reasonable regularization technique is required to overcome the ill - posedness of the problem ; second, we are required to develop a computational efficient technique to reduce the complexity of the solving, which in turn promotes the implementation of the solving algorithm

    目前，逆問題研究中需要解決的關鍵問題是： 1對逆問題中的病態現象，給出一種合理的正則化方法； 2減少逆問題求解所需的計算量，增強求解演算法的可實施性。
  6. This is due to the following two facts : the ill - posedness induced by the incompleteness of the observation data can make the solving much more difficult ; in addition, the observation system involved multiple sensors are required to compensate the inaccuracy of the observation equipment, which will inevitably make the cost of the computation prohibitively expensive

    這是因為，一方面，由觀測數據的不完全性等因素導致的病態現象往往會給逆問題的求解帶來很大困難；另一方面，由於觀測設備自身性能和觀測環境等因素的限制，要獲得更高的估計精度往往需要用多個傳感器對目標進行觀測，這必將給求解逆問題帶來由於計算量過大而難以實現的困難。
  7. However, the major focus of this paper is to strive for the inverse process of the above - mentioned process

    而本文的焦點集中在對正過程的求逆問題上，即重建圖像的過程上。
