The pulse interval modulate technique is used in most of the laser semi-active guided weapons, but the known method of code recognition is inefficient because of its repeated calculation and redundant data. To solve this problem, a new code recognition algorithm was presented, in which the last accumulating condition was selected as the current condition so as to decrease repeating work. This algorithm can recognize the type and the bone cycle of coding accurately, and shorten the decoding time, making the real-time accurate recognition of code in embedded system possible. At the end of the paper, a trial which is made to prove the algorithm efficient, tells the algorithm is better than others in time consuming and it can recognize most of the encoding types.
