Abstract

This paper presents a band adaptive modulation pattern recognition method to against the recognition instability in the electronic war which the signal bandwidth is varying. The method is based on researching decision theory and characteristic parameter. The core of the method is that it can restructure the threshold of parameters with changing signal bandwidth and improve the identification results effectively. The simulation results show that: within signal bandwidth ranging from 1M to 7M, the four modulation patterns can be recognized, recognition rate is more than 95%.
