摘      要:

      This paper develops a method for addressing a novel and application-oriented inverse nodal problem in Sturm-Liouville operators, having significant applications in seismic wave analysis and submarine underwater radar (sonar) detection. Unlike previous works who rely on a dense subset of the nodal set, we propose an optimization framework that recovers the potential $\hat{q}$ from merely a finite set of nodal data, achieving optimal approximation to the target potential $q_0$ while satisfying the nodal constraints.
