Abstract
In trajectory correction fuze of spinning projectiles, the rotating rate experienced by fuze GNSS(Global Navigation Satellite System) receiver causes it positioning inaccurately for the amplitude or phase of signal from them are modulated by rotation. With multi-antenna array, this GNSS Receiver could improve signal-to-noise and anti-interference ability of the system. In addition, the special rotation demodulation loop with three channels helped the GNSS receiver demodulate rotation-modulated signals and thus provided correct position and attitude information. Besides, the quick searching and parallel algorithm realization based on SDR and FPGA were given here. At last, the effect of magnitude and phase modulation and roll rates were simulated, and primary data were obtained. The results show that it can capture and track the rotating projectiles effectively.
