The article presents a method to form the non-periodic selection functions in the short-range coherent pulse Doppler radar information systems with random signal phase-shift keying (manipulation) in transmitting and heterodyne channels. It studies statistical characteristics of Doppler signals received when reflecting from the point object that is located inside the first and arbitrary remote strobes at synchronized random carrier phase-shift keying in transmitting and heterodyne channels. The article shows an expansion of the relative bandwidth of energy spectrum of a Doppler signal received after reflecting from the point object from an arbitrary remote strobe, except for the first one. To form a nonperiodic selection function is possible via the recognition method for the Doppler signal implementations using the relative bandwidth of energy spectrum and via the application of a regression tract to process intervals between zeroes of implementations
