A New Approach to Radar Emitter Recognition Based on Improved Gray Relational Analysis

摘要

Aiming at the deficiency of gray relational analysis method in radar emitter recognition, an improved gray relational analysis method is proposed in this paper. The new method can deal with the situation that the descriptions of some characteristic parameters in database are intervals by improving the calculation process of D-value sequence. At the same time, in order to confirm the weight coefficients of characteristic parameters more effectively, the entropy value analysis method is improved. Simulation results show that the new method has a better recognition rate; moreover, it has a stronger processing ability when some reconnaissance characteristic parameters are default.
