METHOD OF FILTERING AND DETECTING FLUCTUATING RADIOPULSE PACKET |
摘要 |
FIELD: radio engineering. ^ SUBSTANCE: for each radio pulse, a primary adaptive robust estimate of the carrier frequency of the radio pulse is generated; an in-phase long sequence of radio pulses is generated in form of a quasi-harmonic signal; parts of the long sequence that are in-phase for the radio pulses and out of phase for noise are summed; the obtained quasi-harmonic signal is interpolated and based on the smoothed quasi-harmonic signal, using narrowband inertial phase-locked-loop frequency control, both the initial phase and the final estimate of the carrier frequency of the corresponding radio pulse of the packet of the observed mixture are estimated; coherent delay of the processed radio pulse of the observed mixture is carried out until the steady-state condition of the interpolation process is achieved; the processed radio pulse is detected via synchronous detection. ^ EFFECT: high noise-immunity. |
