A method for extracting radar words of multi-function radar at data level

In syntactic modeling, radar words that are encoded into pulse sequences are basic for recognition of multi-function radar(MFR). To deal with the problem of extracting radar words from stream of pulse description word(PDW), an extracting method at data level is presented. Firstly, TTP(TOA to PRI) transform method, a pulse sequence analysis method, is improved and expanded. By combining TOA and the other parameters in PDW, multidimensional figure is obtained for joint identification of radar words. Simulation results show that the intuitive method can reduce the effect of drop pulses and false pulses, and extract the radar words of MFR availably.
