| Popis: | A passive radar system composed of Global Navigation Satellite System (GNSS) satellites and receiver on the ground is introduced. The system detects the target by measuring the Doppler frequency of reflected signal. A Doppler compensation algorithm based on navigation satellite signal divided is presented. The algorithm compensates the Doppler twice by FFT processing with divided signal. It measures the Doppler precisely and extends the Doppler measurement range. The simulation shows that the algorithm is able to acquire desired processing gain and makes it possible to detect the weak signal from target. |
