  Cognitive radar is developed to utilize the feedback of its operating
environment obtained from a beam to make resource allocation decisions by
solving optimization problems. Previous works focused on target tracking
accuracy by designing an evaluation metric for an optimization problem.
However, in a real combat situation, not only the tracking performance of the
target but also its operational perspective should be considered. In this
study, the usage of threats in the allocation of radar resource is proposed for
a cognitive radar framework. Resource allocation regarding radar dwell time is
considered to reflect the operational importance of target effects. The dwell
time allocation problem is solved using a Second-Order Cone Program (SOCP).
Numerical simulations are performed to verify the effectiveness of the proposed
framework.
