Research on Passive Data Association Problems Based on Transmitter Parameters.

Aiming at the defect of traditional passive data association algorithm, a new passive association algorithm flow which can reflect the information of transmitter parameters and target moving status parameters is proposed. A multi-dimensional tracking gate based on the information of transmitter parameters and target moving status parameters is defined in this algorithm. Then fuzzy multi-gate thinking is exerted which used the associated probability with target and its measurements for calculation instead of the feasible associated incident probability in the association algorithm. The simulation indicates that this algorithm is possessed of the merits of less computation time and high accuracy in passive tracking, and especially is suited for representative instances such as short distance, cross-moving targets in complex circumstances.
