The problem of identification of friend-or-foe aircraft in the actual application condition is addressed. A hybrid algorithm combining fuzzy neutral network with probability factor (FNNP), multi-level fuzzy comprehensive evaluation and the Dempster- Shafer (D-S) theory is proposed. This hybrid algorithm constructs a complete process from generating the fuzzy database to the final identification, realizes the identification of friend-or-foe automatically if the training samples or expert’s experience can be obtained, and reduces the effect of uncertainties in the process of identification. At the same time, the whole algorithm can update the identification result with the augment of observations. The performance of the proposed algorithm is assessed by simulations. Results show that the proposed algorithm can successfully deduce the aircraft’s identity even if the observations have measurement errors.
