To study resource management of integrated radio frequency system onboard advanced fighters for “single-to-multiple” jamminga systematic scheme of radar/jamming based on active phased array antenna was analyzedand a model for threat level evaluation was built up by means of multi-attribute decision-making.The jamming task requirement model was established based on the given threat thresholdand time division multiplexing mode was used for jamming multiple targets.An adaptive dynamic resource allocation method was proposed.Two criterions of jamming resource management were proposedthe minimum mean deviation of threat-level and the minimum deviation of highest threat-level.Combined with the algorithm of radar resource managementthe method can be used to realize the integrated management of radar and jamming resources as well.Computer simulation indicated that the adaptive method of resource management could optimize the dynamic allocation of jamming resources.
