The track correlation of airborne radar and ESM is typical heterogeneous sensors track correlation. The traditional correlation

which uses the azimuth as the basis of correlation

cannot satisfy the demands

especially when the targets are too dense. To solve this problem

a new correlation algorithm is proposed

which uses more information

including attribute parameters besides the azimuth. By using multi-factor fuzzy integration decisionmaking

several mathematic models are made to solve the correlation of airborne radar and ESM. The simulation result shows that the three threshold methods have less number of calculation and lower leak probability and false probability.
