摘要：
Global navigation satellite system (GNSS) based multistatic radar is explored for target localization in this paper. Since any point on the earth can be illuminated by a minimum of 4 satellites of each GNSS constellation at any time, GNSS_based passive radar can be inherently considered multistatic radars. In this paper, we focus on the target localization accuracy analysis and CRLB is applied to evaluate the localization accuracy. Two situations, target localization with different number of satellites and target with different signal-to-noise ratio (SNR), are performed to analyze the localization accuracy. Simulation results indicate that a higher localization accuracy can be guaranteed with more satellites. Meanwhile, a higher accuracy can be obtained once the variation range of the echo SNR obtained by different satellites is small.
