Abstract :
A newly-created airport landing system based on passive radar positioning principles is considered in the paper. The proposed system consists of a set of on-ground station receiving the signal sending by on-board transmitter. The central station of this distributed ground passive radar performs one-stage maximum likelihood estimation procedures for combined AOA/TDOA estimation which implements the essence of the system. The potentially achieved accuracy of the deployed prototype system was evaluated by means of simulation for the case of three receiving station equipped with three-dimensional phased array antenna consisting of four concentric antenna rings with 32 elements total. The modular design applied to assembling the receiving station of the system is also under investigation.
