Abstract: To estimate the detonation character of radio fuze and verify the efficiency of processing of signals in fuze processors, zero middle frequency data sampling equipment and fuze data sampling equipment are used to sample all kinds of data in radio fuze trials. Detonation efficiency evaluation software is used to process and analyze the sampled data. Through analysis of the data, the whole process of radio fuze trial is reproduced. A proper signal processing method of radio fuze is found after comparing several kinds of CFAR algorithms. This system can give an overall analysis on the detonation efficiency of radio fuze and provide an important reference to improve the performance of radio fuze processors.
