The invention discloses a rapid MSK communication detection demodulation method, and relates to an easy and rapid MSK communication detection and information blind demodulation reduction method. A user judges whether target communication exists or not and completes information demodulation reduction according to analysis of output signals of a monitoring / reconnaissance receiver in the certain radio environment and extraction of key parameters. The method comprises the steps that a non-cooperative receiver searches for and scans a related frequency band, the computation complexity is low, and software and hardware are easy to obtain. Meanwhile, the information blind demodulation reduction method is a non-coherent detection method. According to the rapid MSK communication detection demodulation method, complex operation processing of carrier phase synchronization is avoided by achieving demodulation reduction of unknown information, meanwhile, the requirement for system carrier frequency estimation accuracy is low, a certain error is allowed to exist in carrier frequency estimation, and the requirements that deviation possibly exists in the working frequency in actual communication and the signal to noise ratio received by non-cooperative communication is low are met.
