Abstract :
In this paper, an approximate real-part sufficiency condition is developed for complex-valued one-dimensional even signals and two-dimensional circularly symmetric signals. The two-dimensional result is used in a reconstruction algorithm which is applied to synthetic and experimental underwater acoustic fields.
