一种新的捕获方法，基于抽取并结合串并行搜索的算法。这种捕获方法在并行码相位搜索算法的基础上加入了抽取和串行搜索的部分，从而减少了计算量，提高了运算速度。- a new capture method, based on the extraction and the combination of serial-parallel search algorithm. The extraction and serial search are added in the capture method on the basis of the parallel code phase search algorithm, thereby reducing the amount of calculation and improving the operation speed.
