Target Localization Based on Bistatic T/R Pair Selection in GNSS-Based Multistatic Radar System

To cope with the increasingly complex electromagnetic environment, multistatic radar systems, especially passive radar, are becoming a trend of future development due to their advantages in anti-electronic jam, anti-destruction properties, and no pollution. However, one problem this multi-source network is that it brings huge amount information leads considerable computational load. Aiming at problem, paper introduces idea selecting external illuminators system. Its essence optimize configuration T/R pairs. Based on this, respectively proposes two optimization algorithms from perspective resolution unit capability, Covariance Matrix Fusion Method Convex Hull Optimization Method, then uses Global Navigation Satellite System (GNSS) as an illuminator verify algorithms. The experimental results show methods significantly improve accuracy positioning, obtain more reasonable use system resources. evaluate algorithm performance under large number transmitting/receiving stations, further simulation was conducted, which combination were applied combined has shown its effectiveness minimize load retain target localization precision same time.
