Abstract：
 There are two isomorphic first and second nodes for processing distance/orientation directions in the imager in real time. The two nodes possess switchable states: state of processing distance direction for distance compression; state of processing orientation direction for orientation focusing. In state of processing distance direction, first and/or second processing nodes carry out distance compression for received data in half frame; and processed results are copied to opposite nodes. After distance compression is completed, state is switched to the state of processing orientation direction. Combining result of distance compression in half frame in own node with result from the opposite node, the method carries out a processing orientation direction for data in one frame. After processing orientation direction is completed, the method outputs imaging result to a main control node for display. Features are: symmetrical structure of imager, high upgradeable and maintainability.
