我们分析了从Hilbert函数空间中初值问题解的时空样本中恢复形式的源项的问题。在h的表达式中,项属于Hilbert空间,而是一个具有指数衰减性的一般实值函数。采样策略的设计考虑了测量中的噪声和背景源的存在。
We analyze the problem of recovering a source term of the formfrom space-time samples of the solutionuof an initial value problem in a Hilbert space of functions. In the expression ofh, the termsbelong to the Hilbert space, whileis a generic real-valued function with exponential decay at. The design of the sampling strategy takes into account noise in measurements and the existence of a background source.
