To improve the non-cooperative weak targets detecting and tracking for monopulse radar in space aircraft launch site, a particle filter track-before-detect method with CFAR based particle weighting is proposed in this paper. The Monte Carlo simulation experiments show that the method can provide 95% tracking with range error less than 6m and velocity error less than 15m/s. And the real data experiments of Tiangong-2 space station show that the method can track non-cooperative weak target stably, and make the tracking range doubled at least.
