High performance track correlation algorithms such as topology sequence method will fail when detection sensor loses target measurements. The area matching algorithm was introduced based on maximum matching support measure and correspondence relation of all targets was optimized. Since the positions of sensor report targets will not differ too much even affected by sensor detection errors, targets in-between distance were adopted as optimization constraint condition to greatly reduce calculation burden. The error match ratio and successful match ratio were simulated under changing target lost ratio for area matching algorithm, which showed good robustness.
