Moving Ship Detection of Inland River Based on GNSS Reflected Signals

This paper explores the possibility of using Global Navigation Satellite Systems (GNSS) as opportunity illuminators in passive bistatic radar systems for the detection of moving target. The main problem of this technology is the restricted power budget provided by navigation satellites, which makes it necessary to improve the signal-to-noise ratio (SNR) of the target’s echo. This paper uses range-Doppler processing to enhance the SNR. After the SNR enhancement, we can calculate the trajectory of the moving target, according to the continuously bistatic range.
