  • Segment correlation-video integration is the most commonly used method for radar signal detection,global positioning system (GPS),and Galileo signal detection.The performance of the segment correlation-video integration method under Doppler shift is analyzed and the processing loss formula is derived. Given the maximum Doppler shift and the carrier-to-noise ratio,the optimum intermediate frequency integration time for the global navigation satellite system (GNSS) receiver is calculated and analyzed based on the minimal mean processing loss criteria.Given the carrier-to-noise ratio of 45 dB-Hz and maximum Doppler shift of 2000 Hz, the mean processing loss is reduced up to 13.5% with the proposed method.

Abstract: Segment correlation-video integration is the most commonly used method for radar signal detection,global positioning system (GPS),and Galileo signal detection.The performance of the segment correlation-video integration method under Doppler shift is analyzed and the processing loss formula is derived. Given the maximum Doppler shift and the carrier-to-noise ratio,the optimum intermediate frequency integration time for the global navigation satellite system (GNSS) receiver is calculated and analyzed based on the minimal mean processing loss criteria.Given the carrier-to-noise ratio of 45 dB-Hz and maximum Doppler shift of 2000 Hz, the mean processing loss is reduced up to 13.5% with the proposed method.
